Abstract
PURPOSE Non-obstructive azoospermia (NOA) is a common, but complex problem, with multiple therapeutic options and a lack of clear guidelines. Hence, there is considerable controversy and marked variation in the management of NOA. This survey evaluates contemporary global practices related to medical and surgical management for patients with NOA. MATERIALS AND METHODS A 56-question online survey covering various aspects of the evaluation and management of NOA was sent to specialists around the globe. This paper analyzes the results of the second half of the survey dealing with the management of NOA. Results have been compared to current guidelines, and expert recommendations have been provided using a Delphi process. RESULTS Participants from 49 countries submitted 336 valid responses. Hormonal therapy for 3 to 6 months was suggested before surgical sperm retrieval (SSR) by 29.6% and 23.6% of participants for normogonadotropic hypogonadism and hypergonadotropic hypogonadism respectively. The SSR rate was reported as 50.0% by 26.0% to 50.0% of participants. Interestingly, 46.0% reported successful SSR in <10% of men with Klinefelter syndrome and 41.3% routinely recommended preimplantation genetic testing. Varicocele repair prior to SSR is recommended by 57.7%. Half of the respondents (57.4%) reported using ultrasound to identify the most vascularized areas in the testis for SSR. One-third proceed directly to microdissection testicular sperm extraction (mTESE) in every case of NOA while others use a staged approach. After a failed conventional TESE, 23.8% wait for 3 months, while 33.1% wait for 6 months before proceeding to mTESE. The cut-off of follicle-stimulating hormone for positive SSR was reported to be 12-19 IU/mL by 22.5% of participants and 20-40 IU/mL by 27.8%, while 31.8% reported no upper limit. CONCLUSIONS This is the largest survey to date on the real-world medical and surgical management of NOA by reproductive experts. It demonstrates a diverse practice pattern and highlights the need for evidence-based international consensus guidelines.

Abstract
PURPOSE Non-obstructive azoospermia (NOA) represents the persistent absence of sperm in ejaculate without obstruction, stemming from diverse disease processes. This survey explores global practices in NOA diagnosis, comparing them with guidelines and offering expert recommendations. MATERIALS AND METHODS A 56-item questionnaire survey on NOA diagnosis and management was conducted globally from July to September 2022. This paper focuses on part 1, evaluating NOA diagnosis. Data from 367 participants across 49 countries were analyzed descriptively, with a Delphi process used for expert recommendations. RESULTS Of 336 eligible responses, most participants were experienced attending physicians (70.93%). To diagnose azoospermia definitively, 81.7% requested two semen samples. Commonly ordered hormone tests included serum follicle-stimulating hormone (FSH) (97.0%), total testosterone (92.9%), and luteinizing hormone (86.9%). Genetic testing was requested by 66.6%, with karyotype analysis (86.2%) and Y chromosome microdeletions (88.3%) prevalent. Diagnostic testicular biopsy, distinguishing obstructive azoospermia (OA) from NOA, was not performed by 45.1%, while 34.6% did it selectively. Differentiation relied on physical examination (76.1%), serum hormone profiles (69.6%), and semen tests (68.1%). Expectations of finding sperm surgically were higher in men with normal FSH, larger testes, and a history of sperm in ejaculate. CONCLUSIONS This expert survey, encompassing 367 participants from 49 countries, unveils congruence with recommended guidelines in NOA diagnosis. However, noteworthy disparities in practices suggest a need for evidence-based, international consensus guidelines to standardize NOA evaluation, addressing existing gaps in professional recommendations.

Abstract
BACKGROUND Digital health has surged during the Covid health crisis, and the use of social media, already prevalent in medicine, has significantly increased. There are Social Networks groups dedicated to physicians with an educational purpose. These groups also facilitate peer discussions on medical questions and the sharing of training materials. OBJECTIVES The aim of our study was to assess the value of these new tools and their contribution to medical education. METHODS An anonymous questionnaire was conducted among members of a Social Networks community group for physicians. The survey received responses from 1451 participants. RESULTS The majority of participants believed they had enriched their medical knowledge and accessed documents they would not have accessed without the group. Subgroup analysis showed that the contribution of this tool is more pronounced for general practitioners and doctors practicing in limited healthcare access. CONCLUSION It is essential to develop digital tools that enhance physician training, and social networks represent a valuable educational tool.

Abstract
PURPOSE The purpose of this meta-analysis is to study the impact of varicocele repair in the largest cohort of infertile males with clinical varicocele by including all available studies, with no language restrictions, comparing intra-person conventional semen parameters before and after the repair of varicoceles. MATERIALS AND METHODS The meta-analysis was performed according to PRISMA-P and MOOSE guidelines. A systematic search was performed in Scopus, PubMed, Cochrane, and Embase databases. Eligible studies were selected according to the PICOS model (Population: infertile male patients with clinical varicocele; Intervention: varicocele repair; Comparison: intra-person before-after varicocele repair; Outcome: conventional semen parameters; Study type: randomized controlled trials [RCTs], observational and case-control studies). RESULTS Out of 1,632 screened abstracts, 351 articles (23 RCTs, 292 observational, and 36 case-control studies) were included in the quantitative analysis. The before-and-after analysis showed significant improvements in all semen parameters after varicocele repair (except sperm vitality); semen volume: standardized mean difference (SMD) 0.203, 95% CI: 0.129-0.278; p<0.001; I²=83.62%, Egger's p=0.3329; sperm concentration: SMD 1.590, 95% CI: 1.474-1.706; p<0.001; I²=97.86%, Egger's p<0.0001; total sperm count: SMD 1.824, 95% CI: 1.526-2.121; p<0.001; I²=97.88%, Egger's p=0.0063; total motile sperm count: SMD 1.643, 95% CI: 1.318-1.968; p<0.001; I²=98.65%, Egger's p=0.0003; progressive sperm motility: SMD 1.845, 95% CI: 1.537%-2.153%; p<0.001; I²=98.97%, Egger's p<0.0001; total sperm motility: SMD 1.613, 95% CI 1.467%-1.759%; p<0.001; l2=97.98%, Egger's p<0.001; sperm morphology: SMD 1.066, 95% CI 0.992%-1.211%; p<0.001; I²=97.87%, Egger's p=0.1864. CONCLUSIONS The current meta-analysis is the largest to date using paired analysis on varicocele patients. In the current meta-analysis, almost all conventional semen parameters improved significantly following varicocele repair in infertile patients with clinical varicocele.

Abstract
PURPOSE Sperm DNA fragmentation (SDF) has been associated with male infertility and poor outcomes of assisted reproductive technology (ART). The purpose of this study was to investigate global practices related to the management of elevated SDF in infertile men, summarize the relevant professional society recommendations, and provide expert recommendations for managing this condition. MATERIALS AND METHODS An online global survey on clinical practices related to SDF was disseminated to reproductive clinicians, according to the CHERRIES checklist criteria. Management protocols for various conditions associated with SDF were captured and compared to the relevant recommendations in professional society guidelines and the appropriate available evidence. Expert recommendations and consensus on the management of infertile men with elevated SDF were then formulated and adapted using the Delphi method. RESULTS A total of 436 experts from 55 different countries submitted responses. As an initial approach, 79.1% of reproductive experts recommend lifestyle modifications for infertile men with elevated SDF, and 76.9% prescribe empiric antioxidants. Regarding antioxidant duration, 39.3% recommend 4-6 months and 38.1% recommend 3 months. For men with unexplained or idiopathic infertility, and couples experiencing recurrent miscarriages associated with elevated SDF, most respondents refer to ART 6 months after failure of conservative and empiric medical management. Infertile men with clinical varicocele, normal conventional semen parameters, and elevated SDF are offered varicocele repair immediately after diagnosis by 31.4%, and after failure of antioxidants and conservative measures by 40.9%. Sperm selection techniques and testicular sperm extraction are also management options for couples undergoing ART. For most questions, heterogenous practices were demonstrated. CONCLUSIONS This paper presents the results of a large global survey on the management of infertile men with elevated SDF and reveals a lack of consensus among clinicians. Furthermore, it demonstrates the scarcity of professional society guidelines in this regard and attempts to highlight the relevant evidence. Expert recommendations are proposed to help guide clinicians.

Abstract
PURPOSE Despite the significant role of varicocele in the pathogenesis of male infertility, the impact of varicocele repair (VR) on conventional semen parameters remains controversial. Only a few systematic reviews and meta-analyses (SRMAs) have evaluated the impact of VR on sperm concentration, total motility, and progressive motility, mostly using a before-after analytic approach. No SRMA to date has evaluated the change in conventional semen parameters after VR compared to untreated controls. This study aimed to evaluate the effect of VR on conventional semen parameters in infertile patients with clinical varicocele compared to untreated controls. MATERIALS AND METHODS A literature search was performed using Scopus, PubMed, Embase, and Cochrane databases following the Population Intervention Comparison Outcome (PICOS) model (Population: infertile patients with clinical varicocele; Intervention: VR [any technique]; Comparison: infertile patients with clinical varicocele that were untreated; Outcome: sperm concentration, sperm total count, progressive sperm motility, total sperm motility, sperm morphology, and semen volume; Study type: randomized controlled trials and observational studies). RESULTS A total of 1,632 abstracts were initially assessed for eligibility. Sixteen studies were finally included with a total of 2,420 infertile men with clinical varicocele (1,424 patients treated with VR vs. 996 untreated controls). The analysis showed significantly improved post-operative semen parameters in patients compared to controls with regards to sperm concentration (standardized mean difference [SMD] 1.739; 95% CI 1.129 to 2.349; p<0.001; I²=97.6%), total sperm count (SMD 1.894; 95% CI 0.566 to 3.222; p<0.05; I²=97.8%), progressive sperm motility (SMD 3.301; 95% CI 2.164 to 4.437; p<0.01; I²=98.5%), total sperm motility (SMD 0.887; 95% CI 0.036 to 1.738; p=0.04; I²=97.3%) and normal sperm morphology (SMD 1.673; 95% CI 0.876 to 2.470; p<0.05; I²=98.5%). All the outcomes showed a high inter-study heterogeneity, but the sensitivity analysis showed that no study was sensitive enough to change these results. Publication bias was present only in the analysis of the sperm concentration and progressive motility. No significant difference was found for the semen volume (SMD 0.313; 95% CI -0.242 to 0.868; I²=89.7%). CONCLUSIONS This study provides a high level of evidence in favor of a positive effect of VR to improve conventional semen parameters in infertile men with clinical varicocele. To the best of our knowledge, this is the first SRMA to compare changes in conventional semen parameters after VR with changes in parameters of a control group over the same period. This is in contrast to other SRMAs which have compared semen parameters before and after VR, without reference to a control group. Our findings strengthen the available evidence and have a potential to upgrade professional societies' practice recommendations favoring VR to improve conventional semen parameters in infertile men.

Abstract
STUDY QUESTION Can ovarian tissue cryopreservation (OTC) be performed after controlled ovarian hyperstimulation (COH)? SUMMARY ANSWER Unilateral oophorectomy after transvaginal oocyte retrieval is feasible on stimulated ovaries during one surgical step. WHAT IS KNOWN ALREADY In the fertility preservation (FP) field, the timeframe between patient referral and start of curative treatment is limited. Combining oocyte pick-up with ovarian tissue (OT) extraction has been reported to improve FP but COH applied before OT extraction is not currently recommended. STUDY DESIGN, SIZE, DURATION This retrospective cohort-controlled study involved 58 patients who underwent oocyte cryopreservation immediately followed by OTC between September 2009 and November 2021. The exclusion criteria were a delay between oocyte retrieval and OTC of >24 h (n = 5) and IVM of oocytes obtained ex vivo in the ovarian cortex (n = 2). This FP strategy was performed either after COH (stimulated group, n = 18) or after IVM (unstimulated group, n = 33). PARTICIPANTS/MATERIALS, SETTING, METHODS Oocyte retrieval followed by OT extraction on the same day was performed either without previous stimulation or after COH. Adverse effects of surgery and ovarian stimulation, mature oocyte yield and pathology findings of fresh OT were retrospectively analysed. Thawed OTs were analysed prospectively, for vascularization and apoptosis using immunohistochemistry, when patient consent was obtained. MAIN RESULTS AND THE ROLE OF CHANCE No surgical complication occurred after OTC surgery in either group. In particular, no severe bleeding was associated with COH. The number of mature oocytes obtained increased after COH (median = 8.5 (25% = 5.3-75% = 12.0)) compared to the unstimulated group (2.0 (1.0-5.3), P < 0.001). Neither ovarian follicle density nor cell integrity was affected by COH. Fresh OT analysis showed congestion in half of the stimulated OT which was higher than in the unstimulated OT (3.1%, P < 0.001). COH also increased haemorrhagic suffusion (COH + OTC: 66.7%; IVM + OTC: 18.8%, P = 0.002) and oedema (COH + OTC: 55.6%; IVM + OTC: 9.4%, P < 0.001). After thawing, the pathological findings were similar between both groups. No statistical difference in the number of blood vessels was observed between the groups. The oocyte apoptotic rate in thawed OT was not statistically different between the groups (ratio of positive cleaved caspase-3 staining oocytes/total number of oocytes equal to median 0.50 (0.33-0.85) and 0.45 (0.23-0.58) in unstimulated and stimulated groups respectively, P = 0.720). LIMITATIONS, REASONS FOR CAUTION The study reports FP from a small number of women following OTC. Follicle density and other pathology findings are an estimate only. WIDER IMPLICATIONS OF THE FINDINGS Unilateral oophorectomy can be successfully performed after COH with limited bleeding risk and an absence of impact on thawed OT. This approach could be proposed to post pubertal patients when the number of mature oocytes expected is low or when the risk of residual pathology is high. The reduction of surgical steps for cancer patients also has positive implications for introducing this approach into clinical practice. STUDY FUNDING/COMPETING INTEREST(S) This work was made possible through the support of the reproductive department of Antoine-Béclère Hospital and of the pathological department of Bicêtre Hospital (Assistance Publique Hôpitaux de Paris, France). The authors have no conflict of interest to disclose in this study. TRIAL REGISTRATION NUMBER N/A.

Abstract
PURPOSE Varicocele is a common problem among infertile men. Varicocele repair (VR) is frequently performed to improve semen parameters and the chances of pregnancy. However, there is a lack of consensus about the diagnosis, indications for VR and its outcomes. The aim of this study was to explore global practice patterns on the management of varicocele in the context of male infertility. MATERIALS AND METHODS Sixty practicing urologists/andrologists from 23 countries contributed 382 multiple-choice-questions pertaining to varicocele management. These were condensed into an online questionnaire that was forwarded to clinicians involved in male infertility management through direct invitation. The results were analyzed for disagreement and agreement in practice patterns and, compared with the latest guidelines of international professional societies (American Urological Association [AUA], American Society for Reproductive Medicine [ASRM], and European Association of Urology [EAU]), and with evidence emerging from recent systematic reviews and meta-analyses. Additionally, an expert opinion on each topic was provided based on the consensus of 16 experts in the field. RESULTS The questionnaire was answered by 574 clinicians from 59 countries. The majority of respondents were urologists/uro-andrologists. A wide diversity of opinion was seen in every aspect of varicocele diagnosis, indications for repair, choice of technique, management of sub-clinical varicocele and the role of VR in azoospermia. A significant proportion of the responses were at odds with the recommendations of AUA, ASRM, and EAU. A large number of clinical situations were identified where no guidelines are available. CONCLUSIONS This study is the largest global survey performed to date on the clinical management of varicocele for male infertility. It demonstrates: 1) a wide disagreement in the approach to varicocele management, 2) large gaps in the clinical practice guidelines from professional societies, and 3) the need for further studies on several aspects of varicocele management in infertile men.

Abstract
Abstract
Background
Polypharmacy is associated with higher rates of adverse drug events and unplanned hospital visits in medical patients. Little is known about polypharmacy in frail older adults undergoing transcatheter (TAVR) or surgical (SAVR) aortic valve replacement.
Purpose
To determine the prevalence and prognostic implications of polypharmacy and potentially inappropriate medications (PIM) following TAVR or SAVR.
Methods
A post hoc analysis of the McGill Frailty Registry was conducted. Patients 70 years of age or older who were discharged alive after TAVR or SAVR at two university hospitals were included. Discharge prescriptions were codified and analyzed using the MedSafer electronic tool that has been validated to flag drug interactions and PIMs considering patient-specific comorbidities. Associations with the primary outcome of 30-day all-cause readmission were examined by logistic regression after adjusting for age, sex, Charlson Comorbidity Index, and procedure type.
Results
The cohort consisted of 495 patients (52% TAVR, 21% isolated SAVR, 27% combined SAVR). The mean age was 80.1±5.5 years with 52% females. The mean number of medications was 10.2±3.7 with 90% having 5 or more medications. A total of 55 patients were readmitted within 30 days. While the total number of medications was not predictive, three specific PIMs were found to be harmful and one PIM was found to be protective for readmission: clopidogrel with warfarin or heparin (OR 3.99; 95% CI 1.47, 10.82), diltiazem with heart failure (OR 3.16; 95% CI 1.04, 36.41), doxazosin or terazosin with hypertension (OR 6.21; 95% CI 0.99, 38.88), and any proton pump inhibitor (OR 0.47; 95% CI 0.26, 0.86). Of note, the combination of clopidogrel with direct oral anticoagulants was not found to be harmful for readmission.
Conclusion
The prevalence of polypharmacy is elevated in older patients undergoing TAVR or SAVR. Specific PIMs, but not total number of medications prescribed, were found to be associated with potentially preventable readmissions.

Abstract
Abstract
Study question
Are parameters of sperm quality part of the prognosis factors for an infertile couple to obtain a live birth when entering an intrauterine insemination program considering repetition of attempts?
Summary answer
Paradoxically, a lower sperm morphology independently predict quick live birth through IUI, as well as younger female age, lower D3 FSH, and higher triggering estradiol.
What is known already
Many studies have highlighted different prognosis factors for obtaining a live birth after IUI involving: male parameters (semen),female parameters (age, parity, ovulation, tubal, and endometriosis status, history of pelvic surgery),couple parameters (duration of infertility, number of previous attempt),IUI parameters (follicle number, endometrial thickness, estradiol at triggering, day of IUI, number of spermatozoa inseminated). However, most of these studies have included small number of attempts, semen parameters were either not collected or assessed with heterogeneity, and repetition of attempts (although iconic for IUI) was not considered, allocating inappropriate weight to cycles which failed in conceiving.
Study design, size, duration
We retrospectively studied the entire cohort of IUI attempts carried out with partner’s sperm at our center between 09/09/2003 and 01/17/2017. We included all male, female, couple and IUI parameters available. Each basic semen analyzes included have been carried out by a restricted number of skilled andrologists from our center. The closest semen assessment performed before IUI was considered as male parameter. IUI attempts were considered repeated unless a live birth or IUI abandonment occurred.
Participants/materials, setting, methods
Our primary outcome was live birth occurrence. We included 2228 couples having performed 5920 IUI attempts, with 636 live births obtained. A mixed logistic regression model was used to take into account IUI repetition before obtaining a live birth. A survival analysis using Cox model, with IUI rank as time variable, live birth as endpoint, and taking into account recurrences was carried out to determine which parameter best predict a quick live birth through IUI.
Main results and the role of chance
Included women were 33.7 ± 4.6 years old in mean. Baseline semen assessment was available for 64% of couples.
Muti-variate analysis showed that live birth was more frequent when: Femal factors: age was young (33 to 38yo, OR 0.76 [0.60;0.96], >38 yo OR 0.49 [0.35;0.67], p = 0.0001), FSH ≤ 8.0 (OR 0.59 [0.45;0.79], p = 0.0002), AMH > 8.9ng/mL (OR 0.59 [0.45;0.79], p = 0.0001), endometriosis was absent (OR 0.56 [0.36;0.88], p = 0.0109), the patient already delivered (OR 1.36 [1.06;1.74], p = 0.0034) Male factors: sperm motility ≤26.0% (OR 0.71 [0.53;0.96], p = 0.0062), sperm vitality ≤72.0% (OR 0.65 [0.47;0.90], p = 0.0032), sperm typical form ≤ 25.0% (OR 0.51 [0.34 ; 0.78], p = 0.0016), IUI attempt factors: total dose of gonadotropin > 495.0 (OR 1.54 [1.26;1.88], p = 0.0001) follicle number > 2 (OR 1.23 [1.69;2.21], p = 0.0296), Estradiol at trigerring > 215.0pg/ml (OR 1.90 [1.53;2.36], p = 0.0001), Endometrial thickness >9.6mm (OR 1.43, p = 0.0024), day of IUI >13 (1.53 [1.24;1.89], p = 0.0001). Using Cox model, couples obtained quickly a livebirth if: woman age was below 33yo: For 33 to 38 yo, OR 0.37 [0.25;0.54], p = 0.0001, >38yo OR 0.19 [0.11;0.32], p = 0.0001 D3 FSH<8 (if above, OR 0.55 [0.34;0.90], p = 0.0160) - Sperm typical form ≤25.0 (if above, OR 0.34 [0.20;0.58], p = 0.0001) Triggering estradiol >215.0pg/ml, OR 1.99 [1.51;2.63], p = 0.0001)
Limitations, reasons for caution
Baseline semen assessment was missing a bit more when cycles were successful, so that a bias connot be excluded. This weird result concerning semen parameters which appear to lower the live birth rate when they are good should thus be considered with caution.
Wider implications of the findings: Good baseline semen parameters do not appear as primordial for obtaining an IUI live birth, and were even found deleterious. However, thresholds highlighted in the present study were high, i.e. of limited clinical mean, and semen below them to remain normal. After confirming, explanations should be investigated: excessive acrosome reaction.

Abstract
In this last century, an increase of men infertility has been registered. It has been suggested that environmental factors could a negative impact over sperm quality. Among these factors, impact of environmental toxicant has been spread by media. In this review of scientific literature, we identify several environmental factors that could impact men fertility in a negative way. These factors are tobacco, marijuana, weight, body mass index, heat, nutritional state, electromagnetic waves and altitude. For each of these factors, the impact over men fertility, their mechanism, as well their influence over the use of Assisted Reproductive Technics are reported.

Abstract
Based on our previous observations that clusterin induction accompanies pancreas regeneration in the rat, we sought to determine if regeneration might be impaired in mice that lacked clusterin. We studied the impact of absent clusterin on morphogenic and functional features of regenerating pancreas. Clusterin induction was accompanied in the regenerating pancreas by a robust development of new lobules with ductules, acini, and endocrine islets in wild type after partial pancreatectomy. In clusterin knock-out mice, however, pancreatectomy resulted in a poor formation of regenerating lobule. In particular, regeneration of beta-cells was also significantly reduced and was associated with persistent hyperglycemia. Duct cells obtained from pancreatectomized clusterin knock-out mice exhibited impaired beta-cell formation in vitro; this was restored by administration of exogenous clusterin. We suggest that clusterin plays a critical role to promote both exocrine and endocrine regeneration following pancreas injury, as well as for in vitro beta-cell regeneration.

Abstract
The apoptotic program incorporates a paracrine component of importance in fostering tissue repair at sites of apoptotic cell deletion. As this paracrine pathway likely bears special importance in maladaptive intercellular communication leading to vascular remodeling, we aimed at further defining the mediators produced by apoptotic endothelial cells (EC), using comparative and functional proteomics. Apoptotic EC were found to release nanovesicles displaying ultrastructural characteristics, protein markers and functional activity that differed from apoptotic blebs. Tumor susceptibility gene 101 and translationally controlled tumor protein (TCTP) were identified in nanovesicle fractions purified from medium conditioned by apoptotic EC and absent from purified apoptotic blebs. Immunogold labeling identified TCTP on the surface of nanovesicles purified from medium conditioned by apoptotic EC and within multivesicular blebs in apoptotic EC. These nanovesicles induced an extracellular signal-regulated kinases 1/2 (ERK 1/2)-dependent antiapoptotic phenotype in vascular smooth muscle cells (VSMC), whereas apoptotic blebs did not display antiapoptotic activity on VSMC. Caspase-3 biochemical inhibition and caspase-3 RNA interference in EC submitted to a proapoptotic stimulus inhibited the release of nanovesicles. Also, TCTP siRNAs in EC attenuated the antiapoptotic activity of purified nanovesicles on VSMC. Collectively, these results identify TCTP-bearing nanovesicles as a novel component of the paracrine apoptotic program of potential importance in vascular repair.

Abstract
Growing evidence suggests that the small intestine may contribute to excessive postprandial lipemia, which is highly prevalent in insulin-resistant/Type 2 diabetic individuals and substantially increases the risk of cardiovascular disease. The aim of the present study was to determine the role of high glucose levels on intestinal cholesterol absorption, cholesterol transporter expression, enzymes controlling cholesterol homeostasis, and the status of transcription factors. To this end, we employed highly differentiated and polarized cells (20 days of culture), plated on permeable polycarbonate filters. In the presence of [(14)C]cholesterol, glucose at 25 mM stimulated cholesterol uptake compared with Caco-2/15 cells supplemented with 5 mM glucose (P < 0.04). Because combination of 5 mM glucose with 20 mM of the structurally related mannitol or sorbitol did not change cholesterol uptake, we conclude that extracellular glucose concentration is uniquely involved in the regulation of intestinal cholesterol transport. The high concentration of glucose enhanced the protein expression of the critical cholesterol transporter NPC1L1 and that of CD36 (P < 0.02) and concomitantly decreased SR-BI protein mass (P < 0.02). No significant changes were observed in the protein expression of ABCA1 and ABCG8, which act as efflux pumps favoring cholesterol export out of absorptive cells. At the same time, 3-hydroxy-3-methylglutaryl-coenzyme A reductase activity was decreased (P < 0.007), whereas ACAT activity remained unchanged. Finally, increases were noted in the transcription factors LXR-alpha, LXR-beta, PPAR-beta, and PPAR-gamma along with a drop in the protein expression of SREBP-2. Collectively, our data indicate that glucose at high concentrations may regulate intestinal cholesterol transport and metabolism in Caco-2/15 cells, thus suggesting a potential influence on the cholesterol absorption process in Type 2 diabetes.

Abstract
Leptin is a hormone that plays a central role in the regulation of food intake and energy expenditure. Originally discovered in mature white adipocytes, it was subsequently isolated from the gastric mucosa. This tissue contains a large number of epithelial endocrine and exocrine cells secreting leptin in the blood stream and in the gastric lumen, respectively. Light and electron microscopy have shown that adipocytes and gastric epithelial cells contain leptin along their rough endoplasmic reticulum-Golgi-granules secretory pathway. Both tissues synthesize a soluble form of the leptin receptor that is secreted bound to leptin in the blood and into the gastric juice. This soluble receptor protect leptin and enhances its half-life. Despite the similarities in the mechanisms of leptin secretion by adipocytes and gastric epithelial cells, they are in fact radically different. In gastric cells leptin follows a rapid regulated secretion pathway whereas adipocytes secrete leptin in a constitutive slow fashion. These differences can be explained by the specific roles play by leptin originating from these two different tissues. Gastric leptin is involved in the short-term regulation of digestion, including delay of gastric emptying, absorption of nutrients by the intestinal wall and secretion of gastric, intestinal and pancreatic hormones. On the other hand, leptin secreted by white adipocytes acts primarily on the hypothalamus for the long-term regulation of food intake. Therefore, the coordination of adipose and gastric leptins ensures the proper management of food processing and energy storage.

Abstract
Diabetic glomerulopathy has been linked to shifts in balance between the synthetic and degradative pathways of the glomerular basement membrane (GBM), a key player in the permselectivity properties of the glomerular wall. The goal of this study was to trace the expression and localization of membrane type-1 metalloprotease (MT1-MMP) and its activating enzyme furin, key proteins involved in basement membrane turnover, in short- and long-term diabetic rat renal tissues. Quantitative immunogold was carried out for MT1-MMP and furin and their expression was evaluated in renal tissues of young and old, control and diabetic rats. To corroborate immunocytochemical findings, Western blots were performed on glomerular lysates. Electron microscopy revealed that the overall expression of MT1-MMP and furin is reduced in plasma membranes of all glomerular cell types of old normoglycemic animals, a phenomenon that is exacerbated in long-term diabetic animals. This observation supports the prevailing theory that diabetes fosters acceleration in the aging process. Interestingly, while biochemical results confirmed a decrease in MT1-MMP expression, an increase in furin was observed. Immunocytochemical studies resolved this discrepancy by tracing the increased furin expression in endoplasmic reticulum and Golgi membranes of podocytes, indicating that furin is retained in the secretory pathway in a diabetic environment. Disturbances at the molecular level of the otherwise tightly regulated MT1-MMP/furin interactions found at the cell surface must account for a lack in extracellular matrix remodeling, increased deposition of GBM material, and loss of glomerular filtration integrity.

Abstract
AIMS/HYPOTHESIS We recently reported that expression of the gene encoding clusterin (Clu) is upregulated in the regenerating pancreas, particularly in tissues undergoing differentiation. This led us to propose that clusterin participates in the cytodifferentiation of pancreatic tissue, particularly the endocrine islet cells. The aim of this study was to investigate whether clusterin induces the differentiation of duct-lining cells into insulin-secreting cells. METHODS We isolated ductal tissue from rat pancreas and cultured it to develop epithelial cell explants for transfection of the Clu cDNA as well as for treatment of clusterin protein. RESULTS The number of newly differentiated insulin cells increased 6.9-fold upon Clu overexpression compared with controls. Ins1 mRNA and peptide levels were also increased. Furthermore, glucose-stimulated insulin secretion was observed in the differentiated insulin cells. These cells were immunoreactive for insulin and C-peptide, but negative for other islet hormones and for cytokeratin-20, which indicates a fully differentiated state. Insulin cell differentiation was also increased in a dose-dependent manner by treating duct cells in culture with clusterin, indicating a growth-factor-like action of clusterin in insulin cell differentiation. CONCLUSIONS/INTERPRETATION These results suggest that clusterin can be considered as a potential morphogenic factor that promotes differentiation of pancreatic beta cells.

Abstract
Persistent hyperglycemia, as occurring in diabetes, induces changes in circulating as well as in structural proteins. These changes involve substitution of lysine residues by glucose adducts resulting in early Amadori products that evolve into toxic and active substances, the advanced glycation end adducts. In previous studies, we demonstrated that early glycated (Amadori) albumin infused into the circulation of normal animals induces transitory alterations of glomerular filtration. Attempting to elucidate the mechanisms underlying these changes, various molecular modifications were introduced in vitro to serum albumin. Glycation, acetylation, carboxymethylation, methylation, and succinylation, involving either a few or a significant number of amino acid residues, produced heavier and more anionic albumin molecules compared with the native one. Native and each of the modified albumin molecules were injected intravenously into normal rats, followed, 30 min later, by hapten-tagged native BSA. Changes in glomerular filtration were evaluated by morphometrical analysis of gold immunolabelings. Compared with native albumin, all the modified forms of albumin induced a deeper penetration of the tracer through the glomerular basement membrane revealing alterations in glomerular permselectivity. This was more evident for severely modified albumin molecules which displayed high labelings in the urinary space and endocytic compartments of proximal tubule epithelial cells. These results indicate that modifications of serum albumin, even minimal, as those occurring in early diabetes, could immediately affect the permselectivity properties of the glomerular wall leading, with time, to severe glomerulopathies.

Abstract
Stem cells in adult pancreas and their specific marker are poorly characterized. We hypothesized that pancreatic stem cells could evolve from the duct system in response to neogenic stimulation and may transiently express nestin during tissue regeneration. After partial pancreatectomy (Px), we found extensive formation of ductules consisting of nestin-positive epithelial cells with higher replicating ability in the neogenic foci, particularly at day 3 after Px. Nestin was highly expressed in the earlier stages of ductule morphogenesis and then regressed as the cells evolved toward differentiated pancreatic cell types. The neogenic ductules were isolated for the culture of nestin-positive duct stem cells. These nestin-positive duct cells were numerous and displayed extensive self-replication in the duct cell explants after 2-3 days of culture, thus depicted as nestin-positive duct stem (NPDS) cells. As seen in the tissue of neogenic foci, NPDS cells were negative for cytokeratin-20 and vimentin, the marker for duct epithelial and mesenchymal cells, respectively. Endocrine cells, mostly insulin cells, were present in the explants at day 2 as single cells or as small clusters adjacent to the NPDS cells, and formed islet-like masses at day 3 of culture, suggesting islet cell differentiation from NPDS cells. In addition, insulin secretion from these beta cells responded to glucose stimulation. We found transient up-regulation of PDX-1 expression by reverse transcriptase-polymerase chain reaction at day 3 after Px in pancreatic tissue. Higher expression of PDX-1 was seen in the culture of neogenic ductules than that of ducts isolated from the sham-operated pancreas. In particular, a subpopulation of nestin-positive cells in the duct cell explants formed from the neogenic ductules expressed PDX-1 in their nuclei. Taken together, this information suggests that NPDS cells could be generated from adult pancreas by neogenic motivations and they may differentiate into insulin-secreting cells.

Abstract
Aiming to discern the mechanisms by which circulating
glycated albumin alters the glomerular filtration properties
that lead to glomerular dysfunction in diabetes, the authors
studied the distribution and densities of anionic charges
through the rat glomerular wall upon intravascular infusion
of Amadori products, as well as in various conditions of
increased glomerular permselectivity. Polylysine-gold was
used as the probe to reveal the anionic charges. The study
was carried on renal tissue sections of bovine serum albumin
(BSA)- and glycated BSA–injected, normoglycemic
animals. Results were generated through morphometrical
evaluations of the gold labeling. Changes in glomerular anionic
distribution were corroborated on renal tissue sections
of short- and long-term diabetic rats and of normal newborn
rats, situations known for abnormal glomerular filtration.
Altered renal function in these conditions was clearly
associated with changes in glomerular anionic charges. On
the other hand, the infusion of glycated albumin in the circulation
of normal rats, though altering glomerular filtration
properties, did not modify the distribution and density of
the polylysine-gold labeling through the glomerular basement
membrane. Thus, anionic charges seem not to be the
factor involved in the early changes of glomerular permeability
induced by circulating glycated albumin.

Abstract
In pancreatic acinar cells, chaperonin Cpn60 is present in all the cellular compartments involved in protein secretion as well as in mitochondria. To better understand the role Cpn60 plays in pancreatic secretion, we have evaluated its changes under experimental conditions known to alter pancreatic secretion. Quantitative protein A-gold immunocytochemistry was used to reveal Cpn60 in pancreatic acinar cells. Cpn60 immunolabelings in cellular compartments involved in secretion were found to decrease in acute pancreatitis as well as upon stimulation of secretion and in starvation conditions. A major increase in Cpn60 was recorded in diabetic condition. This was normalized by insulin treatment. Although in certain situations changes in secretory enzymes and in Cpn60 correlate well, in others, nonparallel secretion seemed to take place. In contrast, expression of mitochondrial Cpn60 in acinar cells appeared to remain stable in all conditions except starvation, where its levels decreased. Expression of Cpn60 in the secretory pathway and in mitochondria thus appears to behave differently, and Cpn60 in the secretory pathway must be important for quality control and integrity of secretion.

Abstract
Renin and angiotensinogen have been previously found in the rat pancreas, and angiotensin receptors have been located in the apical domain of duct cells. To evaluate the possibility that angiotensin II could be generated within the duct system, we decided to determine whether angiotensinogen is present in rat pancreatic juice and the angiotensinogen-immunoreactive pancreatic cell types that could be responsible for its production. Angiotensinogen was detected in significant amounts by Western blotting in pancreatic juice collected from several individual rats. Different isoforms between plasma and pancreatic juice angiotensinogens were demonstrated by isoelectric focusing. Immunocytochemical experiments revealed angiotensinogen-immunoreactive cells at the periphery of the islets of Langerhans, and confocal microscopy demonstrated that most angiotensinogen-immunoreactive cells were glucagon-secreting cells. Secretion of angiotensinogen did not follow the regulated secretory pathway since it was absent from the glucagon-containing granules. This was confirmed by electron microscopy immunocytochemistry. Duct and acinar cells did not express angiotensinogen at an immunocytochemical detectable level. The present findings indicated an exocrine secretion of angiotensinogen by glucagon-secreting cells and suggest that one of the final targets of the local pancreatic renin-angiotensin system may be the duct epithelium.

Abstract
AIMS/HYPOTHESIS We undertook the characterization of the capillary bed of the rat frontal cortex and their permeability properties in short-term and long-term diabetic rats. METHODS Diabetes was induced by strepozotocin injection. Rats were maintained hyperglycaemic without insulin treatment during 4 to 5 months (short-term) and 8 to 13 months (long-term). Rats from an additional short-term hyperglycaemic group received an injection of exogenous dinitrophenylated albumin 15 min before being killed. Tissues were processed for electron microscopy and quantitative immunocytochemistry. Endogenous and dinitrophenylated exogenous albumin were revealed with high resolution over the capillary wall using specific antibodies and the protein A-gold complex. Morphometrical analyses were carried out. RESULTS Albumin is transported across endothelial cells by plasmalemmal vesicles or caveolae and larger vacuolar structures. This transport increased in diabetic rats by an increment in the number of vesicles. Albumin distribution across the capillary basement membrane showed that the restrictive properties of the basement membrane present in normoglycaemic rats are altered in the diabetic condition, as was its thickness. Similar alterations of the basement membrane structure and function were encountered in old normoglycaemic rats but to a lesser extent. CONCLUSION/INTERPRETATION The results indicate that diabetes seems to accelerate the ageing process of the vascular wall and that the central nervous system capillary bed is also a target for diabetic microangiopathy.

Abstract
With the rete model of the eel swimbladder, we have studied the appearance and development of a microangiopathy during a 2-year period of hyperglycaemia. Hyperglycaemia was induced in the eel by chronic exposure to cold water. At 3-5 months, basement membrane thickness was twice the normal value and increased only slightly thereafter. Diffusion coefficients of permeability were measured in counter-current perfusion experiments for a variety of tracers that are believed to use different pathways of transcapillary transport. The permeability to sucrose was the first to significantly increase, at 6-8 months, followed by that of albumin, insulin, and inulin, at 9-11 months and that of sodium, at 18-24 months. The permeability to water and antipyrine remained stable throughout the study. The results indicate that in the rete model, chronic hyperglycaemia induces a rapid thickening of the capillary basement membrane and selective permeability increments in the various paths of transcapillary transport.

Abstract
Vitronectin, a multifunctional glycoprotein present in blood and extracellular matrix, is not only a member of the cell adhesion molecules, but also a regulator of proteolytic enzyme cascades, thereby providing a unique regulatory factor for proteolytic degradation of extracellular matrix and tissue remodeling. Vitronectin interacts with the cell surface through integrins of the alpha(v)-related system. Because vitronectin and its receptor may have a role in various renal physiological and pathological processes, we evaluated their expression in renal tissues of streptozotocin-induced short- and long-term hyperglycemic rats by applying quantitative immunoelectron microscopy and Western blot analysis. Vitronectin was shown over the glomerular basement membrane (GBM) and mesangial matrix (MM), whereas alpha(v) was located along the plasma membrane of endothelial, epithelial, and mesangial cells. Although distribution patterns of vitronectin and alpha(v) integrin labeling in renal tissues from short- and long-term hyperglycemic rats, as well age-matched normoglycemic rats, were similar, increases in their immunoreactive sites were detected in hyperglycemic conditions. Changes also were present in old compared with young normoglycemic animals. The diabetes-related increase in vitronectin was more significant in the GBM than MM, whereas the increase in alpha(v) integrin was as significant in podocytes as mesangial cells. Western blot analysis, performed on isolated glomerular material from normoglycemic and hyperglycemic animals, confirmed those changes. Our results suggest that vitronectin and its receptor, alpha(v) integrin, must have defined roles in molecular mechanisms involved in the pathogenesis of both diabetic and aging nephropathy.

Abstract
In previous studies, we have shown that the bile-salt-dependent-lipase (BSDL), secreted by pancreatic acinar cells and secreted into the duodenal lumen, can be transcytosed through intestinal cells up to the lamina propria. In this study, we used an in vitro system to provide insights into the apical to basolateral transport of BSDL, across the intestinal barrier. The Int407 human epithelial cell line, grown under conditions that optimize polarity, was used as a tight epithelium model. We attempted to delineate uptake mechanisms and the transcytotic pathway followed by this pancreatic enzyme within the intestinal Int407 cells, which do not produce BSDL. When added to the apical reservoir of Transwell-grown Int407 cells, BSDL was shown to first interact with the apical membrane. Further, BSDL forms clusters that are internalized via clathrin-coated pits. Following endocytosis, BSDL is directed to a nocodazole- and colchicin-sensitive multivesicular compartment. Interestingly, this protein transits through the Golgi apparatus, where it was found to colocalize with the KDEL retrieval-receptor. Finally, enzymatically active intact BSDL was released at the basolateral membrane level. This is the first demonstration for an apical-to-basolateral transcytotic pathway of a secreted pancreatic digestive enzyme through polarized intestinal cells.

Abstract
It has been established that leptin displays a number of effects on peripheral tissues. We have investigated the effect of the hormone on lipid synthesis, apolipoprotein biogenesis and lipoprotein secretion in Caco-2 cells. Immunocytochemistry revealed the presence of leptin receptors (Ob-Rb) on the basolateral membrane. Incubation of cells with 200 nM leptin resulted in a decreased export of triglycerides in the basolateral medium without affecting monoglyceride, diglyceride and cholesterol ester lipid classes. It also significantly reduced the output of de novo-synthesized apolipoprotein (Apo)B-100 and ApoB-48 as well as that of newly formed chylomicrons and of low-density lipoproteins. It also enhanced that of ApoA-I, ApoA-IV and ApoE. Our results support the hypothesis that leptin can affect energy balance at the gut level by reducing lipid release into the circulation.

Abstract
In the central nervous system, the primary targets of the human immunodeficiency virus-1 (HIV-1) are microglia, resulting in a disorder called HIV-1 dementia. P-glycoprotein (P-gp), a membrane-associated ATP-dependent efflux transporter, limits entry into the brain of numerous xenobiotics, including anti-HIV drugs (i.e., protease inhibitors). This project investigates the functional expression of P-gp in the endogenous immune cells of the brain, a parenchymal compartment not previously studied. We used a cell line (MLS-9) derived from rat microglia to study the transport of digoxin, a known P-gp substrate. Reverse transcriptase-polymerase chain reaction analysis detected mRNA for only mdr1b in MLS-9 cells, whereas both mdr1a and mdr1b mRNA were expressed in primary cultured microglia from which they were derived. Western blot analysis with the C219 antibody detected a single band at ~170 to 180 kDa in MLS-9 cells, which is the size previously reported for P-gp. Immunocytochemical analysis with the monoclonal antibodies C219, MRK16, and MAB-448 labeled P-gp protein along the plasma membrane and nuclear envelope of MLS-9 cells. [3H]Digoxin accumulation by monolayers of MLS-9 cells was significantly enhanced in the presence of any of several P-gp inhibitors (verapamil, cyclosporin A, quinidine, PSC 833), protease inhibitors (i.e., saquinavir, indinavir, and ritonavir), and sodium azide, an ATPase inhibitor. These results provide the first evidence for the functional expression of P-gp in microglia and imply that entry of pharmacological agents, including protease inhibitors, may be prevented within the brain parenchyma, as well as at the blood-brain barrier.

Abstract
Intestinal and liver fatty acid binding proteins (I- and L-FABP) are thought to play a role in enterocyte fatty acid (FA) trafficking. Their modulation by cell differentiation and various potential effectors was investigated in the human Caco-2 cell line. With the acquisition of enterocytic features, Caco-2 cells seeded on plastic progressively increased L-FABP quantities, whereas I-FABP was not detectable even very late in the maturation process. On permeable filters that improved differentiation markers (sucrase, alkaline phosphatase, transepithelial resistance), Caco-2 cells furthered their L-FABP content and expressed I-FABP. Western blot analysis showed a significant increase in I- and L-FABP expression following an 8-hour incubation period with butyric acid, oleic acid, and phosphatidylcholine. However, in all cases, I-FABP levels were higher than L-FABP concentrations regardless of the lipid substrates added. Similarly, hydrocortisone and insulin enhanced the cellular content of I- and L-FABP whereas leptin triggered I-FABP expression only after an 8-hour incubation. Finally, tumor necrosis factor-alpha was more effective in increasing the cytosolic amount of I-FABP levels. In conclusion, our data demonstrate that I-FABP expression is limited to fully differentiated Caco-2 cells and can be more easily regulated than L-FABP by lipids, hormones, and cytokines.

Abstract
AIMS/HYPOTHESIS Studies on the functional and morphological relations between exocrine and endocrine pancreas have been conducted mainly to disclose the influence of islets of Langerhans on acinar parenchyma. Less attention has been paid to the relations occurring between islets and pancreatic ducts. METHODS A series of consecutive sections of normal adult rat pancreas were double stained with islet (hormones) and duct (cytokeratin 20) markers. Electron microscopy was conducted to investigate the ultra-structural features of duct-islet relations and anti-insulin immunogold labelling was carried out to reveal the presence of insulin in the pancreatic duct system. RESULTS Consecutive double-stained sections demonstrated that 73.60 +/- 2.97% of the islets were attached to the ducts. For each series, 93.48 +/- 5.43 % of the islets contacting the duct tree were associated with small-sized ducts or centroacinar cells. Electron microscopy revealed that some insulin and somatostatin cells do face the duct lumen. Insulin was detected within the duct lumen and in the endosomal compartment of the duct cells. CONCLUSIONS/INTERPRETATION The finding that most islets are connected with the duct system in the adult pancreas is discussed in terms of hormone secretion into the ducts, islet histogenesis and the relation among the three tissue components of the pancreas, the endocrine, the exocrine and the duct system.

Abstract
The needs to precisely assign macromolecules to specific locations and domains within tissues and cells and to reveal antigens which are present in low or even in trace amounts, led to the elaboration of a wide spectrum of immunocytochemical amplification procedures. These arise from the successive improvements of tissue preparation techniques, of antigen retrieval procedures and of immunological or non-immunological detection systems. Improvement of detection systems may be the most active in the development of amplification techniques. Since the early work of Coons, in which by the introduction of the indirect technique has started amplifying the signal, different systems have succeeded in increasing the sensitivity of antigens detection. Indeed, amplification techniques such as the multiple antibody layers, the multiple bridges, the enzyme complexes, the avidin-biotin, the silver intensification, and the numerous variations and combinations among these have increased the sensitivity for the detection of scarce tissue antigens. However, as shown by the recent progress carried out with new approaches such as the catalyzed reporter deposition (CARD) and the enhanced polymer one-step staining (EPOS), more efficient methods are still needed. In electron microscopy, few techniques have reached the resolution afforded by the post-embedding immunogold approach. In spite of this and in order to further increase its sensitivity, new probes and novel approaches are allowing combination of the gold marker with the amplification capacity of enzymes afforded by the CARD technique. Immunogold amplification strategies, such as the multiple incubations with the primary antibody and the use of an anti-protein A antibody have also led to enhanced signals displaying the advantages in terms of resolution and possibilities of quantification inherent to the colloidal gold marker.

Abstract
Previous studies have established a preferential glomerular filtration of glycated BSA (gBSA), as well as a facilitated filtration of BSA in the presence of gBSA. We intend to determine whether these modifications are permanent or transitory. gBSA was intravenously injected into anesthetized normal mice and maintained in circulation for 30 min, 1, 2, 24, and 48 h. Five minutes before death, FITC-BSA was injected. On immunocytochemical evaluations, increased glomerular filtration of FITC-BSA was found at all circulating time points. Changes at 24 and 48 h were less pronounced. Glomerular basement membrane (GBM)-to-lumen gBSA labeling ratios were similar at all time points suggesting no accumulation of gBSA in the GBM. Seventy percent of the gBSA was cleared from the circulation and the GBM after 24 h, and 95% after 48 h. This was confirmed in experiments with radiolabeled tracers. These results suggest that the alteration in GBM permeability to BSA in the normal mouse are due to the presence of gBSA and are gradually overcome along with its clearance from circulation. In early diabetes, increasing concentrations of circulating glycated proteins could be responsible for changes in glomerular permselectivity and probably for the alteration in glomerular filtration properties leading to diabetic nephropathy.

Abstract
By applying the highly sensitive cytochemical Gautron's technique, we were able to reveal AChE activity in rat pancreatic acinar cells, particularly at the level of a complex membrane-bound network formed by tubules with varicosities located around the nuclei and close to the basolateral membrane. The Golgi apparatus was devoid of cytochemical reaction beside the trans-Golgi network cisternae, which showed a positive reaction. The RER of some acinar cells also presented a signal, demonstrating their capability of synthesizing AChE. Immunogold using a specific anti-AChE antibody yielded similar results. Double-labeling experiments corroborated the presence of enzyme cytochemical and immunocytochemical signals in the same lysosomal tubular network. Biochemical sedimentation assays confirmed the presence of AChE in acinar cells, which exists as two globular molecular forms, G(1) and G(4). These results were obtained with pancreatic tissue in situ as well as with isolated acinar cells maintained in culture and devoid of neural elements. The existence of a continuous tubular lysosomal network containing AChE is in agreement with previous reports on acinar and other cell types, and supports a more general hypothesis on dynamic continuities among cell structures. Whether AChE is being secreted by the acinar cells or internalized through this endo-lysosomal system was not defined. However, the capability of the acinar cells to synthesize AChE and to channel it through a tubular system is a good indication that the cells can modulate their cholinergic stimulation for optimal secretion of digestive enzymes.

Abstract
In the present article we review several postembedding cytochemical techniques using the colloidal gold marker. Owing to the high atomic number of gold, the colloidal gold particles are electron dense. They are spherical in shape and can be prepared in sizes from 1 to 25 nm, which renders this marker among the best for electron microscopy. In addition, because it can be bound to several molecules, this marker has the advantage of being extremely versatile. Combined to immunoglobulins or immunoglobulin-binding proteins (protein A), it has been applied successfully in immunocytochemistry. Colloidal gold particles 5-15 nm in size are excellent for postembedding cytochemistry. Particles of smaller size, such as 1 nm, must be silver enhanced to be visualized by transmission electron microscopy. We have elected to review the superiority of indirect immunocytochemical approaches using IgG-gold or protein A-gold (protein G-gold and protein AG-gold). Lectins or enzymes can be tagged with colloidal gold particles, and the corresponding lectin-gold and enzyme-gold techniques have specific advantages and great potential. Using an indirect digoxigenin-tagged nucleotide and an antidigoxigenin probe, colloidal gold technology can also be used for in situ hybridization at the electron microscope level. Affinity characteristics lie behind all cytochemical techniques and several molecules displaying high affinity properties can also be beneficial for colloidal gold electron microscopy cytochemistry. All of these techniques can be combined in various ways to produce multiple labelings of several binding sites on the same tissue section. Colloidal gold is particulate and can easily be counted; thus the cytochemical signal can be evaluated quantitatively, introducing further advantages to the use of the colloidal gold marker. Finally, several combinations and multiple step procedures have been designed to amplify the final signal which renders the techniques more sensitive. The approaches reviewed here have been applied successfully in different fields of cell and molecular biology, cell pathology, plant biology and pathology, microbiology and virology. The potential of the approaches is emphasized in addition to different ways to assess specificity, sensitivity and accuracy of results.

Abstract
This review focuses on the contribution of molecular chaperones in the secretory process of digestive enzymes and their interaction with enterocytes. By using biochemistry and immunocytochemistry, we have shown that Grp94, Cpn10, Cpn60, and protein disulfide isomerase (PDI) are present all along the rough endoplasmic reticulum-Golgi-granule secretory pathway of the pancreatic acinar cells and are secreted into the acinar lumen. Two other molecular chaperones, Grp78 and the Hsp70, appear to be restricted to the rough endoplasmic reticulum and the trans-Golgi apparatus, respectively. We have found that chaperones can be associated with pancreatic enzymes along the secretory pathway. Indeed, double immunogold and immunocoprecipitation revealed an association between Cpn60 and the colipase-dependent lipase (CDL) and between Grp94 and the bile salt-dependent lipase (BSDL). These complexes are secreted into the acinar lumen and diverted to the duodenal lumen. These findings led us to investigate these enzyme-chaperone complexes in intestinal tissue. Grp94, Cpn60, and PDI are present on microvilli and on the endosomal compartment of enterocytes. Furthermore, we have shown that the Grp94-BSDL complexes are internalized by enterocytes through classical endocytosis. Upon dissociation of the BSDL-Grp94 complex in the late endosome, BSDL is transferred to the basolateral membrane. We propose that Grp94 interacts with specific receptors and/or could force the associated protein to adopt a specific conformation that allows its binding to corresponding membrane receptors and its internalization by enterocytes. These two hypotheses need not to be exclusive. The existence of such a pancreatic secretion-intestinal absorption link speaks in favor of a coordinated functional connection between these two entities, through molecular chaperones, in order to optimize intestinal activities.

Abstract
The alteration induced by diabetes on vascular permeability to serum albumin was investigated in the mesentery of streptozotocin-induced hyperglycemic rats. Double-tagged ((125)I and dinitrophenol-haptenated) heterologous albumin was intravenously administered in normal and hyperglycemic animals, and the extravasation of the tracer was evaluated by radioactivity measurements and by morphometry at the ultrastructural level using quantitative protein A-colloidal gold immunocytochemistry. The results demonstrate that diabetes induces a significant increase in the permeability of the mesentery vessels to albumin. This increase is due to a more efficient transport of macromolecules by endothelial plasmalemmal vesicles and not to leakier interendothelial junctions. Passage across the endothelial basement membranes did not appear to be restricted in either the control or diabetic condition. However, in diabetes, the mesothelial basement membrane appeared to become modified and to restrain the passage of albumin toward the peritoneal cavity. After 3 months of diabetes, the rats presented a net increase in the average diameter of the blood vessels localized in the mesentery arcada (macrovascular hyperplasy) and a notable angiogenesis, manifested at the level of the microvasculature in the mesenteric windows.

Abstract
Many of the mechanisms that control insulin processing and packaging by interaction with different elements along the secretory pathway remain poorly understood. We have investigated the possibility that Cpn60, a member of the heat shock protein family, may be present in rat insulin-secreting cells, participating in the proinsulin-insulin maturation process. Immunofluorescence and high resolution immunocytochemical studies revealed the presence of the Cpn60 protein all along the insulin secretory pathway, being particularly abundant over the proinsulin-containing immature secretory granules. Double-labeling experiments showed associations between Cpn60 and proinsulin, as well as between Cpn60 and PC1 convertase, with a preferential binding to proinsulin. These findings paralleled those of coimmunoprecipitation studies showing the Cpn60 chaperone and the mature form of the PC1 convertase in proinsulin immunoprecipitates, as well as the PC1 in Cpn60 immunoprecipitates from total islet cell extracts. In vitro binding of Cpn60 to proinsulin, insulin and glucagon was also documented. Cpn60, significantly abundant in proinsulin-containing secretory granules where conversion of proinsulin to insulin takes place, and the colocalization of the chaperone with proinsulin and PC1 convertase suggest that the Cpn60 protein may play a role directing precise molecular interactions during insulin processing and/or packaging.
