Comparison of outcomes between intracytoplasmic sperm injection and in vitro fertilization inseminations with preimplantation genetic testing for aneuploidy, analysis of Society for Assisted Reproductive Technology Clinic Outcome Reporting System data. Fertil Steril 2024; 121:799-805. [PMID: 38185201 DOI: 10.1016/j.fertnstert.2023.12.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 12/22/2023] [Accepted: 12/29/2023] [Indexed: 01/09/2024]
Abstract
OBJECTIVE To evaluate whether insemination via intracytoplasmic sperm injection (ICSI) provides any benefit over in vitro fertilization (IVF) insemination for nonmale factor infertility with respect to preimplantation genetic testing (PGT) results and pregnancy outcome. DESIGN Retrospective cohort study of the Society for Assisted Reproductive Technology database. SETTINGS US-based fertility clinics reporting to the Society for Assisted Reprodcutive Technology. PATIENTS Patients undergoing IVF or ICSI inseminations in nonmale factor PGT for aneuploidy cycles. INTERVENTION In vitro fertilization vs. ICSI inseminations. MAIN OUTCOME MEASURES Primary outcomes were the percentage of embryos suitable for transfer and live birth rates (LBRs). Secondary outcomes included subgroup analysis for embryos suitable for transfer on cycles from patients ≥35-year-old vs. <35-year-old, ≤6 oocytes retrieved vs. >6 oocytes retrieved, and unexplained infertility. Additionally, gestational age at delivery and birth weight between IVF and ICSI inseminations were evaluated. RESULTS A total of 30,446 nonmale factor PGT diagnoses for aneuploidy cycles were evaluated, of which 4,867 were IVF inseminations and 25,579 were ICSI inseminations. Following exclusion criteria and adjustment for any necessary confounding variables, no significant differences existed in embryos suitable for transfer between IVF and ICSI treatment cycles, 41.6% (40.6%, 42.6%) vs. 42.5% (42.0%, 42.9%), respectively, or in LBRs, 50.1% (37.8, 62.4%) vs. 50.8% (38.5%, 62.9%), respectively. CONCLUSION There were no significant differences in the rates of embryos suitable for transfer and LBRs between IVF and ICSI inseminations in nonmale factor cycles undergoing PGT for aneuploidy.

Abstract
Purpose: To determine the relationship between pubertal development and postpubertal gonadal function in childhood cancer survivors. Methods: Childhood cancer survivors (≥10 years of age) who received follow-up care in a pediatric oncology group in an academic medical center during the period from January 1, 1985, to July 1, 2010 were included in this case series. Their pubertal development and gonadal function were evaluated. Results: The cohort consists of 39 males (age 10-21 years) and 35 females (age 10-29 years) with a variety of cancer diagnosis and treatments. The average age at diagnosis was ∼7.5 years. The average age at the time of the study was 16 and 16.7 years in males and females, respectively, representing a mean follow-up interval of ∼9 years. Despite the fact that 60% of survivors received cyclophosphamide equivalents and 16.2% received cranial radiation or brain tumor resection, the majority of survivors (68%) presented with both normal puberty and normal gonadal functions at the time of follow-up. In 27% of survivors, puberty development did not predict gonadal function in early adulthood: 20% of survivors had normal puberty, but abnormal gonadal function; 7% of survivors had abnormal puberty, but gonadal function remained normal as young adults. Conclusions: Most childhood cancer survivors had normal puberty and gonadal function despite a variety of cancer treatment modalities. However, normal puberty did not predict normal gonadal function later in life in many survivors. Therefore, close follow-up with gonadal function in adolescent and early adulthood years is essential.

The impact of using donor sperm in assisted reproductive technology cycles on perinatal outcomes. Fertil Steril 2019; 110:1285-1289. [PMID: 30503127 DOI: 10.1016/j.fertnstert.2018.08.012] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2018] [Revised: 08/01/2018] [Accepted: 08/02/2018] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To assess the impact of using donor sperm in assisted reproductive technology (ART) cycles on perinatal outcomes. DESIGN Historical cohort study. SETTING US national database from the Society of Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) from 2012 to 2013. PATIENT(S) Patients undergoing the first fresh autologous ART cycle using either donor or partner sperm. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Miscarriage, preterm birth, low birthweight rates. RESULTS A total of 134,710 fresh autologous ART cycles were evaluated from the SART CORS database. Following exclusion criteria and after restricting to the first cycle, 2,123 donor sperm and 42,799 partner sperm ART cycles were included in the final analyses. After adjusting for all confounding variables (including maternal age, race, body mass index, smoking status, gravidity, history of preterm birth, highest follicle stimulating hormone count, blastocyst transfer percentage, total embryo transferred, and etiology of infertility), no statistically significant differences in miscarriage rates, preterm births, very preterm births, low birthweight, and very low birthweight were observed. Birthweight was significantly lower in the partner sperm group than in the donor sperm group (3,292 ± 601 and 3,233 ± 592 g in donor and partner sperm groups, respectively, adjusted P value 0.003); however, this small absolute difference (adjusted effect estimate 42 g, 95% CI 14.7-70.9) does not carry clinical significance. CONCLUSIONS The use of donor sperm in fresh autologous ART cycles was not associated with increased miscarriage, preterm births, or low birthweights, as compared to cycles using partner sperm. This information can be used in patient counseling to reassure patients using donor sperm in ART cycles.

Abstract
OBJECTIVE To study the differences in perinatal outcomes after frozen embryo transfer cycles using autologous or donor oocytes in women of advanced maternal age. DESIGN Historical cohort study. SETTING US national database from the Society of Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) from 2009 to 2013. PATIENT(S) Women at 40-43 years of age undergoing autologous frozen embryo transfers (a-FET) or donor oocyte frozen embryo transfers (d-FET) resulting in singleton pregnancies that were entered in the SART CORS database from 2009 to 2013. RESULTS a-FET resulted in 4402 singleton live births whereas d-FET resulted in 2703 singleton live births. d-FET resulted in a higher risk of preterm births (< 37 weeks), with adjusted odds ratio (aOR) 1.33 (95% CI 1.02-1.75), but similar risk of small for gestational age (SGA), with aOR 1.75 (95% CI 0.85-3.7), when compared to a-FET. However, when only single blastocyst transfer cycles are considered, d-FET and a-FET showed no difference in preterm births or other adverse perinatal outcomes. CONCLUSIONS Singletons resulting from d-FET are at increased risk for perinatal morbidity. However, the risk was diminished in single blastocyst transfer cycles. Our study supports the current American Society for Reproductive Medicine (ASRM) guidelines of transferring a single blastocyst in d-FET cycles.

Abstract
Reproductive aging is a natural process that occurs in all women, eventually leading to reproductive senescence and menopause. Over the past half century there has been a trend towards delayed motherhood. Postponing reproduction can increase the chance of a woman remaining involuntarily childless as well as an increase in pregnancy complications in those that do achieve pregnancy at advanced maternal age. Despite the well-documented decrease in fecundity that occurs as a woman ages, reproductive aged women frequently overestimate the age at which a significant decline in fertility occurs and overestimate the success of assisted reproductive technologies (ART) to circumvent infertility. Oocyte cryopreservation enables women to achieve genetically related offspring in the event that they desire to postpone their childbearing to an age after which a significant decline in fertility occurs or in circumstances in which their reproductive potential is compromised due to medical pathology. Available success rates and safety data following oocyte cryopreservation have been reassuring and is not considered experimental according to the American Society for Reproductive Medicine and the European Society for Human Reproduction and Embryology. This review article will focus on an evidence-based discussion relating to reproductive aging and oocyte cryopreservation.

Abstract
PURPOSE What are the experience, approach, and knowledge of US Obstetricians and Gynecologists' (ob-gyn) towards counseling patients on reproductive aging (RA) and elective fertility preservation (EFP). METHODS A cross-sectional survey emailed by the American College of Obstetricians and Gynecologists (ACOG) to 5000 ACOG fellows consisting of 9 demographic and 28 questions relating to counseling patients on RA and EFP. RESULTS Seven hundred and eighty-four responders completed the survey. Although 82.8% agreed that conversations relating to RA should take place with patients desiring future childbearing and delaying due to social reasons, only 27.6% stated that they frequently counsel these women aged 18-34 years old, compared to 75.8% aged 35-44 years old (P < 0.01). Limited time (75.8%) and limited knowledge (41.4%) were amongst the most frequent reported barriers towards counseling patients on RA. Fifty-eight percent stated that they have been asked about EFP by patients. Although 74.8% agreed that conversations should take place related to EFP in women desiring future childbearing and delaying due to social reasons, only 27.6% stated that they frequently counsel these patients on EFP (P < 0.01). Limited time (75%) and limited knowledge (59.9%) were amongst the most frequent barriers towards counseling on EFP. CONCLUSIONS In the USA, methods to improve patient counseling and provider knowledge on RA and EFP are warranted and further studies are needed to address optimal methods to improve counseling and knowledge related to these topics.

Abstract
Single-gene mutations account for more than 6000 diseases, 10% of all pediatric hospital admissions, and 20% of infant deaths. Down syndrome and other aneuploidies occur in more than 0.2% of births worldwide and are on the rise because of advanced reproductive age. Birth defects of genetic origin can be diagnosed in utero after invasive extraction of fetal tissues. Noninvasive testing with circulating cell-free fetal DNA is limited by a low fetal DNA fraction. Both modalities are unavailable until the end of the first trimester. We have isolated intact trophoblast cells from Papanicolaou smears collected noninvasively at 5 to 19 weeks of gestation for next-generation sequencing of fetal DNA. Consecutive matched maternal, placental, and fetal samples (n = 20) were profiled by multiplex targeted DNA sequencing of 59 short tandem repeat and 94 single-nucleotide variant sites across all 24 chromosomes. The data revealed fetal DNA fractions of 85 to 99.9%, with 100% correct fetal haplotyping. This noninvasive platform has the potential to provide comprehensive fetal genomic profiling as early as 5 weeks of gestation.

Abstract
A contributing factor to poor placental perfusion, leading to intrauterine growth restriction and preeclampsia, is the failure of invading extravillous trophoblast (EVT) cells to remodel the maternal uterine arteries during the first and second trimesters of pregnancy. Noninvasive assessment of EVT cells in ongoing pregnancies is possible beginning three weeks after conception, using trophoblast retrieval and isolation from the cervix (TRIC). Seven proteins were semi-quantified by immunofluorescence microscopy in EVT cells obtained between gestational weeks 6 and 20 from pregnancies with normal outcomes (N = 29) and those with intrauterine growth restriction or preeclampsia (N = 12). Significant differences were measured in expression of PAPPA, FLT1, ENG, AFP, PGF, and LGALS14, but not LGALS13 or the lineage marker KRT7. These findings provide for the first time direct evidence of pathology-associated protein dysregulation in EVT cells during early placentation. The TRIC platform provides a novel approach to acquire molecular signatures of EVT cells that can be correlated with pregnancy outcome.

Abstract
Congenital adrenal hyperplasia (CAH) is an autosomal recessive defect in cortisol biosynthesis that elevates fetal androgen levels to cause genital ambiguity and external genital masculinization in newborn females. Introducing dexamethasone in utero by 7 weeks gestation precludes virilization of affected females. However, identification of a male fetus prior to week 7 could avert the necessity of steroid treatment in half of pregnancies at risk of CAH. We recently introduced trophoblast retrieval and isolation from the cervix (TRIC), an approach that noninvasively isolate homogeneous trophoblast cells from pregnant women as early as 5 weeks gestation, using a Papanicolaou test. Here, we have used TRIC to correctly identify male fetal DNA when both parents were carriers of the mutation that produces CAH and previously produced an affected child. Trophoblast cells (1400) obtained by TRIC were assessed using immunocytochemistry with an antibody against the trophoblast-specific β subunit of human chorionic gonadotropin, which labeled 100% (17 of 17) of isolated cells, while none of the excluded maternal cervical cells were labeled. The isolated cells were examined by fluorescent in situ hybridization for chromosomes 18, X, and Y at a clinical cytogenetics laboratory, demonstrating 100% (18 of 18) of cells to be diploid 18/XY. Aliquots of DNA obtained from the isolated cells assayed for SRY and RNASEH genes by TaqMan assays confirmed a male fetus. This case study demonstrates the utility of TRIC to accurately identify fetal gender as a means of reducing the need for prophylactic administration of exogenous steroids in pregnancies at risk of CAH.

Abstract
OBJECTIVE The objective of this study is to evaluate whether trophoblast yield obtained by trophoblast retrieval and isolation from the cervix (TRIC) is affected by pregnancy outcome, gestational age (GA) at retrieval, maternal body mass index (BMI), parity, or maternal age. METHODS TRIC was performed on 224 ongoing pregnancies between 5 and 20 weeks of GA. Trophoblast cells were isolated from cervical cells using anti-human leukocyte antigen-G antibody coupled to magnetic nanoparticles. Purity was assessed by the percentage of isolated cells that express β-hCG. Patient records were monitored until delivery, and pregnancy outcomes were determined. Trophoblast yield was compared with GA at time of collection, maternal BMI, parity, maternal age, and outcome of pregnancy, using linear regression. RESULTS There was no effect of GA, maternal BMI, parity, and maternal age on trophoblast yield. Trophoblast yield decreased significantly with early pregnancy loss compared with uncomplicated pregnancies that delivered at term. Trophoblast yield with preeclampsia or intrauterine growth restriction was decreased compared with healthy term outcomes; however, they did not reach statistical significance. CONCLUSIONS If TRIC becomes available as a method for non-invasive prenatal testing, our data demonstrate that it is unaffected by BMI and is useful as early as 5 weeks of GA.

Abstract
INTRODUCTION The epidermal growth factor (EGF) signaling system regulates trophoblast differentiation, and its disruption could contribute to perinatal disease. We hypothesized that this pathway is altered in preeclampsia, a disorder associated with trophoblast apoptosis and failure to invade and remodel the uterine spiral arteries. METHODS Six EGF family peptides and a truncated EGF receptor splice variant (p110/EGFR) were examined using immunohistochemistry in the trophoblast of placentas (N = 76) from women with preeclampsia, and compared to placentas from women of similar gestational age (GA) with preterm labor (PTL) or small for gestational age (SGA) fetuses, as well as normal term placentas. EGF, transforming growth factor-α (TGFA), and heparin-binding EGF-like growth factor (HBEGF) were evaluated using ELISA in maternal plasma from another 20 pregnancies with or without preeclampsia. Cell death was evaluated in the HTR-8/SVneo human cytotrophoblast cell line using TUNEL to evaluate the protective effects of EGF peptides. RESULTS Trophoblast HBEGF, TGFA, and EGF were significantly reduced in preeclampsia compared to PTL and SGA, while p110/EGFR accumulated significantly on the surface of the chorionic villi (p < 0.05). Plasma EGF levels were significantly decreased in preeclamptic patients, compared to non-preeclamptic patients (p < 0.05). HBEGF, EGF, TGFA, epiregulin, and betacellulin each blocked cytotrophoblast cell death in vitro (p < 0.05). DISCUSSION Three members of the EGF family are dysregulated in placentas with preeclampsia, whereas p110/EGFR, a potential EGF receptor antagonist, is overexpressed. These findings are consistent with the concept that disruption of the EGF signaling system contributes to aberrant trophoblast development associated with preeclampsia.

Abstract
In a prospective randomized fashion, this study evaluated embryo development in vitro after defragmentation versus assisted hatching alone of low grade day 3 embryos. Although a sustained decrease in day 5 fragmentation was observed in the defragmented group versus the assisted hatching only group, no difference in compaction rates or blastula formation rates were appreciated.

Abstract
BACKGROUND AND STUDY AIMS The aim of this observational study was to perform the first epidemiology study in a primary care patient population with GERD in the Grand Duchy of Luxembourg and to evaluate the added value of the GERD Impact Scale (GIS) patient questionnaire. PATIENTS AND METHODS 152 Patients with symptoms of GERD from 20 study centers were included. At visit 1, demographic data including lifestyle factors and the patients' symptoms were recorded. GERD symptoms and their severity, treatment changes and the GIS were all assessed at baseline (visit 1), visit 2 (4-6 weeks) and visit 3 (8-14 weeks). Analyses were performed on an intent-to-treat basis. RESULTS 142 patients were included in the analysis, which comprised 50% men and 50% women with a mean BMI of 27 kg/m2. Documented lifestyle factors included consumption of caffeine-containing beverages (87% of patients), stress (62%) and alcohol consumption (53%); 44% of patients were smokers or ex-smokers. The median duration of GERD was 2.0 years. Upon inclusion, 46% were receiving, or had received, proton pump inhibitors (PPIs), antacids (44%), H2-receptor antagonists (21%) or no treatment (21%). PPIs were prescribed at the first visit in the majority of cases (94%) with 75% of patients being prescribed esomeprazole with a median daily dose of 40 mg. The GIS score correlated well with the clinician's judgment of symptom severity and was reported to help determine the appropriate treatment and evaluate the patient's response in approximately 80% of patients. CONCLUSIONS In this, the first epidemiological study on GERD patients in the Grand Duchy of Luxembourg, data was obtained as planned. The novel patient questionnaire was judged to be helpful by the physician and data shows that the GIS may have an added value over current assessments.

Abstract
This study was conducted to compare different liquid culture media for Paenibacillus larvae growth in order to find the best one to be used in studies on activity of antimicrobial substances, such as essential oils. P. larvae presented poor growth in usual broths such as Mueller-Hinton, commonly employed in antimicrobial activity assays. Growth in liquid media was evaluated using Paenibacillus larvae strains isolated from hives located in different geographical zones. The MYT medium (Mueller-Hinton broth, yeast extract and thiamine) was selected out of the eight liquid media analyzed, as it proved to be the most adequate due to its higher absorbance at 620 nm. The following mean values were obtained from the four P. larvae strains: 0.227 +/- 0.016 for the Cobo strain, 0.279 +/- 0.015 for La Plata strain, 0.758 +/- 0.020 for Mechongué strain and 0.244 +/- 0.0079 for Sierra de los Padres strain, respectively.

Abstract
This study assessed the susceptibility of Escherichia coli to the antimicrobial activity of honeys by different techniques. Honeys used were from the southeast region of Buenos Aires province. In order to evaluate antimicrobial activity against Escherichia coli ATCC 25922, solutions containing 0, 1, 5, 10, 25 and 50% (w/v) of honey were prepared. Liquid media (Mueller-Hinton and Mac Conkey broths) were used to assess the Minimal Inhibitory Concentration (MIC) by the serial dilution test. The minimal bactericidal concentration (MBC) was determined by counting on nutritive and Mac Conkey agar. In addition, for the evaluation of total antibacterial activity, the agar diffusion method was used. A reduction of microbial growth of 96% in Mueller-Hinton broth and of 90% in Mac Conkey broth by honey solutions containing 50% and 25% (w/v), was respectively observed. The bactericide action of honey in nutritive agar proved negative. The MBC value in Mac Conkey agar was 25% (w/v) of honey. The methods used for measuring the antibacterial activity in the present work were adequate to prove that honeys are active against E. coli at 25 and 50% (w/v) concentrations. The results obtained by the dilution method with Mueller-Hinton broth and the agar diffusion method were both concordant.

Abstract
In vitro antimicrobial activity of a mixture of two essential oils and thymol against Paenibacillus larvae, causal agent of American Foulbrood (AFB), was evaluated. The essential oils were extracted from cinnamon (Cinnamomum zeylanicum) and thyme (Thymus vulgaris). The third component used, thymol, is the major component of the essential oil of thyme which contains 39.9% of thymol. Minimal inhibitory concentration (MIC) in Mueller-Hinton broth by the tube dilution method and minimal bactericide concentration (MBC) on MYPGP agar were evaluated. Thyme registered MIC values of 150-250 microg/ml and MBC values of 200-300 microg/ml, while the MIC and MBC values obtained for cinnamon were of 50-100 microg/ml and 100-125 microg/ml. Thymol showed similar MIC and MBC values of 100-150 microg/ml. No significant differences between the bacterial strains were detected, but significant differences between essential oils and thymol activity were registered (P<0,01). An inhibitory synergetic effect on AFB was observed reducing MIC and MBC values due to the use of a mixture of 62.5% of thyme, 12.5% of cinnamon and 25% of thymol.

Abstract
The central nucleus of the amygdala (CeA) is generally regarded as a control nucleus of subcortical target systems. Due to its widespread projections to different brain areas it is able to modulate emotional behavior of the organism. However, it is still not clear whether single neurons of the CeA project to different areas or to one target area. Injections of the retrograde tracers Fluorogold and True Blue into target regions of the central nucleus of the amygdala, i.e., the substantia innominata (SI) and the caudal pontine reticular nucleus (PNC), revealed overlapping but otherwise distinct neuronal populations within mainly the medial division of the CeA. From our study we conclude that SI and PNC receive input from different subsets of amygdala neurons.

Abstract
The human major histocompatibility complex (MHC) class I chain-related gene A (MICA), located 46 kb centromeric to HLA-B, encodes a stress-inducible protein, which is a ligand for the NKG2D receptor. In addition to its primary role in immune surveillance, data suggest that MICA is involved in the immune response to transplants and in susceptibility to some diseases. In this study, 152 subjects from the Yoruba (n=74), Efik (n=32), and Igbo (n=46) tribes of southern Nigeria, 39 nationwide African-American stem cell donors, and 60 African-American individuals residing in the metropolitan Boston area were studied for MICA, HLA-B allelic variation, haplotypic diversity, and linkage disequilibrium (LD). MICA and HLA-B exhibited a high degree of genetic diversity among the populations studied. In particular, MICA allele and HLA-B-MICA haplotype frequencies and LD in the Efik and Igbo tribes were significantly different from the other study groups. HLA-B and MICA loci demonstrated significant global LD in all five populations (P-values &<0.00001). LD also varied in a haplotype-specific manner. A novel MICA allele was detected in the Boston population. These findings are important from an anthropologic perspective, and will inform future HLA-linked disease association studies in related ethnic groups of African-derived ancestry.

Abstract
A microbiological study during the process and the storage of garlic (Allium sativum L.) and onion (Allium cepa L.) dehydrated, with the additional barriers of blanching or brine immersion, was made. In all raw materials the average counts of aerobic mesophilic bacteria expressed in CFU/g ranged from 1.2 x 10(2) to 1.6 x 10(3), molds and yeasts from 60 to 1.6 x 10(3), Lactobacillus spp. and Leuconostoc mesenteroides subsp. mesenteroides between 10 and 50. Microorganisms identified were Penicillium spp., Monilia spp., Lactobacillus brevis, Leuconostoc mesenteroides subsp. mesenteroides and yeasts in garlic; Mucor spp., Penicillium spp., Monilia spp., Lactobacillus brevis and yeasts in both types of onions. Leuconostoc mesenteroides subsp. mesenteroides was detected in only kind of onion. In dehydrated garlic storage, Penicillium spp., Monilia spp., Lactobacillus brevis and yeasts were detected. In garlic, when a blanching step was carried out no microflora was detected. Mucor spp., Penicillium spp., Monilia spp. and Lactobacillus brevis were identified in both types of dehydrated onions. When brine immersion was included the microflora detected was significantly lower and only Penicillium spp. were found. The use of additional barriers such as blanching or brine immersion produces an important effect on the microbiological stability in these products.

Abstract
OBJECTIVE To report the magnetic resonance (MR) imaging findings of enlarged veins in the spinoglenoid notch as a cause of suprascapular nerve compression. DESIGN AND PATIENTS Six patients presented to MR imaging for evaluation of chronic shoulder pain. Clinical information and MR imaging studies were reviewed. The spinoglenoid notch vascular structures were compared with measurements made in 10 age-matched controls. RESULTS Spinoglenoid notch vascular structures measured in 10 asymptomatic age-matched control patients ranged from 1 to 4 mm in diameter with an average of 2.2 mm. The six study patients had vascular structures that ranged from 6 to 10 mm in diameter with an average of 8.4 mm. Atrophy and fatty infiltration of the infraspinatus muscle was noted as an associated finding at MR imaging in all six patients. Surgery was performed in three of the six patients, at which time a venous varix was identified in the spinoglenoid notch in all three patients. CONCLUSION We describe distended veins in the spinoglenoid notch. These may be readily apparent at MR imaging and should be distinguished from paralabral ganglion cysts compressing the suprascapular nerve in the absence of labral tears, especially if percutaneous aspiration of a ganglion cyst is entertained.

Abstract
Myelin basic proteins (MBP) are major constituents of the myelin sheath of oligodendrocytes and Schwann cells in the central nervous system and the peripheral nervous system, respectively. We previously showed that MBP-related transcripts are present in the bone marrow and the immune system. These mRNAs are transcribed from a region called 0', consisting of three exons, located upstream of the classical MBP exons; these three exons belong to the long MBP gene otherwise called "Golli-MBP." The most abundant of these mRNAs, now called HMBP (hemopoietic MBP), encompasses the sequence encoded by the region 0' plus exon 1 and part of intron 1 of the classic MBP gene. Antisera to recombinant HMBP proteins are immunoreactive with proteins of about 26-28 kDa in brain, thymus, and spleen. This report demonstrates that HMBP proteins are present in the vast majority (>95%) of thymic T cells, which express the corresponding transcripts, as do mature T cells from lymph nodes and spleen. HMBP mRNAs and proteins are also manifest in the majority of spleen B lymphocytes and in B cell lines. In addition to lymphoid cells, HMBP proteins are in all types of myeloid lineage cells, i.e., macrophages, dendritic cells, and granulocytes, as well as in megakaryocytes and erythroblasts. Finally, HMBP proteins are present in CD34+ bone marrow cells, and, furthermore, in highly proliferative cultures, these CD34+ cells express HMBP RNAs and proteins. Thus, MBP gene products are present both in the nervous system and in the entire hemopoietic system.

Abstract
Freshly milled wheat flour has a pale yellow color due to its carotenoids content. Benzoyl peroxide is a bleaching agent typically used to give such flour a better appearance. This free-radical initiator promotes carotenoids oxidation, thereby producing less colored compounds, and benzoic acid is a main final product. Samples of wheat flour were treated with 150 ppm of benzoyl peroxide to begin a bleaching process, and then subjected to ethyl ether extraction at different intervals of time. Benzoyl peroxide and benzoic acid levels in these extracts were monitored by means of HPLC in individual experiences. The resulting concentration of benzoyl peroxide after 9 days of contact with the bleaching agent was 11 ppm, dropping afterward to nondetectable levels. A maximum value for benzoic acid of 16 ppm was found after 12 h of bleaching. Subsequently this level decreased continuously until reaching a residual value of 6 ppm after 3 months.

Abstract
To further understand the role of cytokine responses in symptom formation and host defenses in influenza infection, we determined the levels of IL-1beta, IL-2, IL-6, IL-8, IFN-alpha, TGF-beta, and TNF-alpha in nasal lavage fluid, plasma, and serum obtained serially from 19 volunteers experimentally infected with influenza A/Texas/36/91 (H1N1) and correlated these levels with various measures of infection and illness severity. We found that IL-6 and IFN-alpha levels in nasal lavage fluids peaked early (day 2) and correlated directly with viral titers, temperature, mucus production, and symptom scores. IL-6 elevations were also found in the circulation at this time point. In contrast, TNF-alpha responses peaked later (day 3 in plasma, day 4 in nasal fluids), when viral shedding and symptoms were subsiding. Similarly, IL-8 peaked late in the illness course (days 4-6) and correlated only with lower respiratory symptoms, which also occurred late. None of IL-1beta, IL-2, or TGF-beta levels increased significantly. These data implicate IL-6 and IFN-alpha as key factors both in symptom formation and host defense in influenza.
