Abstract
BACKGROUND Medical infrared thermal imaging (IRT) has been applied to research blood flow, breast cancer detection, and human body muscle performance. The benefits of IRT include the fact that it is noninvasive, quick, dependable, non-contact, capable of creating several recordings in a short period of time, and secure for both patients and medical professionals. We aimed to determine the predictive value of IRT for identifying and evaluating any interventional procedure in patients affected by peripheral artery disease (PAD) of any severity. METHODS We searched the Cochrane Library, EMBASE, and PubMed on the topic of IRT and PAD until January 20,2023. We excluded gray literature as it is lacking credibility for not undergoing a peer-reviewed process. The search strategy includes the medical topic headings for "infrared thermal imaging" and "peripheral vascular disorders." The primary outcome of this systematic review was the variation in tissue perfusion in PAD patients. Each technique's technical characteristics and therapeutic use within PAD must be described in each included study. RESULTS This systematic review included 2 case reports and 3 observational studies. By comparing the temperatures of PAD patients hands, legs, and feet, IRT might prove to be an unduly valuable tool for treating vascular illnesses, especially in light of the knowledge gained from the temperature distribution maps. CONCLUSION This noninvasive method demonstrated encouraging results in the detection of various areas of foot perfusion and the screening of PAD, and it gave good findings in gauging the effects of any type of intervention.

Abstract
Partial-thickness rotator cuff tears (PTRCTs) are often found in daily orthopedic practice, with most of the tears occurring in middle-aged patients. An anaerobic process and imbalanced oxygenation have been observed in PTRCTs, resulting in oxidative stress. Studies have shown the roles of oxidative stress in autophagy and the potential of unregulated mechanisms causing disturbance in soft tissue healing. This article aims to review literature works and summarize the potential pathology of oxidative stress and unregulated autophagy in the rotator cuff enthesis correlated with chronicity. We collected and reviewed the literature using appropriate keywords, in addition to the manually retrieved literature. Autophagy is a normal mechanism of tissue repair or conversion to energy needed for the repair of rotator cuff tears. However, excessive mechanisms will degenerate the tendon, resulting in an abnormal state. Chronic overloading of the enthesis in PTRCTs and the hypovascular nature of the proximal tendon insertion will lead to hypoxia. The hypoxia state results in oxidative stress. An autophagy mechanism is induced in hypoxia via hypoxia-inducible factors (HIFs) 1/Bcl-2 adenovirus E1B 19-kDa interacting protein (BNIP) 3, releasing beclin-1, which results in autophagy induction. Reactive oxygen species (ROS) accumulation would induce autophagy as the regulator of cell oxidation. Oxidative stress will also remove the mammalian target of rapamycin (mTOR) from the induction complex, causing phosphorylation and initiating autophagy. Hypoxia and endoplasmic reticulum (ER) stress would initiate unfolded protein response (UPR) through protein kinase RNA-like ER kinase (PERK) and activate transcription factor 4, which induces autophagy. Oxidative stress occurring in the hypovascularized chronic rotator cuff tear due to hypoxia and ROS accumulation would result in unregulated autophagy directly or autophagy mediated by HIF-1, mTOR, and UPR. These mechanisms would disrupt enthesis healing.

Abstract
Aim To determine the effect of secretome hypoxia mesenchymal stem cells (SH-MSCs) on the relative gene expression of hypoxia inducible factor-1a (HIF-1a) and basic fibroblast growth factor (bFGF) in accelerating histomorphometric repair of tendon to bone interface healing in rats acute rotator cuff tear (RCT) model. Methods This is experimental research with posttest control group design. Thirty-male Wistar rats were divided into five treatment groups: healthy group and rotator cuff reconstruction group included four groups: SH-MSCs W2 (the treatment group was given a SH-MSCs 0.5 mL and terminated at weeks 2), NaCl W2 (the control vehicle group was given NaCl 0.5 mL and terminated at weeks 2), SH-MSCs W8 (the treatment group was given a SH-MSCs 0.5 mL and terminated at weeks 8), and NaCl W8 (the control vehicle group was given NaCl 0.5 mL and terminated at weeks 8). On the termination day, all the rats were terminated and HIF-1a and bFGF gene expression were analysed using qRT-PCR. Results SH-MSCs significantly increased the HIF-1a and bFGF gene expression than NaCl group even in week 2 and week 8. The highest increased gene expression of HIF-1a and bFGF was on week 8. Conclusion SH-MSCs are important in the healing repair process of tendon-to-bone interface in acute RCT model rats through increasing gene expression of HIF-1α and bFGF.

Abstract
BACKGROUND Dementia is a neurocognitive disorder associated with the aging brain and mainly affects the hippocampus and cerebral cortex. The Hippo signaling pathway and autophagy proteins have been found to be perturbed in the brain affected by dementia processes. OBJECTIVE This systematic review aims to elaborate on the involvement of the Hippo signaling pathway and autophagy in modulating the progression and severity of dementia in aging. METHODS Searches were conducted on MEDLINE, Google Scholar, Scopus, and Web of Science databases. RESULTS The Hippo signaling pathway is dependent upon the transcriptional co-activator YAP/TAZ, which forms complexes with TEAD in the nucleus in order to maintain cell homeostasis. When the expression YAP/TAZ is reduced, transcriptional repression-induced atypical cell death, ballooning cell death, and necrosis will consequently occur in the neurons. Moreover, the autophagic proteins, such as LC3, ATG proteins, and Beclin, are reduced, resulting in the disruption of autophagosome formation and accumulation and the spread of misfolded proteins in the brain suffering from dementia. CONCLUSION The impairment of the Hippo signaling pathway and autophagy in the dementia process in aging should be considered since it might predict the severity, treatment, and prevention of dementia.

Abstract
Objectives In order to treat a rat model of rotator cuff rupture, this work concentrated on the expression of TNMD and RUNX2, followed by rotator cuff repair and secretome-hMSCs. Methods A total of thirty 10-weeks-old male Sprague-Dawley rats were separated into five groups randomly, RC on week 0, lesion treated with a rotator cuff repair and saline (RC + NaCl group, n = 6) for 2 and 8 weeks, and lesion treated with a rotator cuff repair and secretome-hMSCs (RC + secretome-hMSC group, n = 6) for 2 and 8 weeks. The supraspinatus and infraspinatus muscle-tendon units were obtained for histological and biomechanical investigation at 0, 2 and 8 weeks following injury. Results The findings showed that, in comparison with the RC + NaCl group, secretome-hMSCs significantly improved tendon repair by upregulating TNMD and RUNX2 expression and histology score. Conclusion Combining Secretome-hypoxia MSCs with RC healing may help rats with rotator cuff tears.

Abstract
Background Knee osteoarthritis (OA) is a chronic and progressive degenerative disease. It resulted from mechanical and chemical disorders that damage the joint and the underlying bone. The management of knee OA is challenging due to poor self-regeneration of connective tissues. Surgical treatment with prolotherapy approaches was conducted to treat medial compartment knee OA. Aim To know the injection frequency to reach a 50% improvement in VAS score and WOMAC index. Methods Six patients who suffered from late-stage medial compartment knee OA underwent PFO followed by twelve sessions of intra-articular dextrose prolotherapy. The subjective pain score, visual analog scale (VAS), was assessed based on the patient subjectiveness before and after treatment. Patients marked the score from 0 to 10 cm to describe the current pain state. The functional index, the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index used to evaluate the Patient's clinical symptoms. It ranges from 0 to 96 points consisting of three main sections: pain (total 20 points), stiffness (total: eight points), and physical function disability (total 68 points). Higher scores indicate severe symptoms and function. Results Four patients showed pain relief and functional improvement with more than 50% scores of VAS and WOMAC after the treatment. Two patients received more than twelve doses of intra-articular dextrose prolotherapy due to a lack of progress. Conclusion This study provides clinical evidence for a new treatment strategy for advanced knee OA. This combined therapy improves the patient's daily activity function and postpones the need for total knee arthroplasty (TKA).

Abstract
Hydrodilation of the glenohumeral joint is commonly employed as a nonsurgical intervention for the frozen shoulder. Accuracy and pain during the procedure can be regarded as difficulties in performing this procedure. Ultrasonography (USG) guided injection and suprascapular nerve block can improve the accuracy and can decrease pain during the hydrodilation procedure. We present the step-by-step method for performing USG-guided injections for suprascapular nerve block and hydrodilation.

Abstract
Introduction and importance Peripheral nervous system involvement is very common in Sjogren's syndrome (SS); however, polyradiculopathy has been reported rarely in association with SS, and predominantly chronic forms have been described. Here, we reported a case from our Neurosurgery Department in Intan Medika KIM Hospital, Bangka Island, Pangkalpinang, Indonesia; as Academic Health System of Universitas Padjadjaran. Case presentation A 32-year-old woman, diagnosed with Sjogren's syndrome that was characterized by anti-nuclear, anti-Ro, anti-La and anti dsDNA-antibodies positives since 3 years ago; consulted to our department for a chronic low back with a radicular pain in both lower limbs from the gluteal area to both feet together with numbness, hyperstesis and allodynia. The pain was evaluated by the visual analogue scale (VAS) score of 8; we then performed cervico-lumbal computed tomography (CT) scan that demonstrated multiple protruded discs of the cervical- and lumbar-spine. Clinical discussion Pain was treated with lumbar interlaminar epidural steroid injections as a safe technique that allows relieving patient symptoms; after 10 min, the patient experienced an improvement in her pain with reduced scores to 0–1 in VAS, as well as a significant improvement on her quality of life later on. Conclusion The use of lumbar interlaminar epidural steroid injections for an alternative therapeutic for neuropathic pain in SS gives a satisfactory result in terms of improvement of pain as well as a significant improvement on patients' quality of life. Ten to fifteen percent of the Sjogren’s syndrome patients present with polyneuropathy pain involvement. Pain treated with lumbar interlaminar epidural steroid injections is a safe technique for relieving the symptoms. Interlaminar epidural block is an alternative therapy management for neuropathic pain in Sjogren’s syndrome.

Abstract
Propolis is a resinous beehive product that has a wide range of biological activities, namely antimicrobial, antioxidant, and anti-inflammatory properties. Propolis is collected by the bees from plant resin and exudates to protect hives and maintain hive homeostasis. The aim of the present systematic scoping review is to explore the potential and suitability of propolis as an adjunctive treatment in breast cancers, based on the latest available experimental evidence (2012-2021). After applying the exclusion criteria, a total of 83 research publications were identified and retrieved from Scopus, Web of Science, and Pubmed. Several relevant key themes identified from the included studies were cytotoxicity, synergistic/combination treatment, improvement in bioavailability, human clinical trials, and others. A majority of the studies identified were still in the in vitro and in vivo stages. Nonetheless, we managed to identify 4 human clinical trials that demonstrated the successful use of propolis in alleviating side effects of chemotherapy and radiotherapy while increasing the quality of life of breast cancer patients, with minimal adverse effects. In conclusion, propolis, as an adjunctive treatment, may have therapeutic benefits in alleviating symptoms related to breast cancers. However, further clinical trials, preferably with higher number of participants/subjects/patients, are urgently needed.

Inclusion criteria were English-language studies reporting the results of pain improvement, functional outcome scores, and radiographic examinations after repair of bursal side partial rotator-cuff tears at any time point in patients of any age and with all levels of evidence. Exclusion criteria were articles not in English, in vitro or animal studies, epidemiological studies, and such article types as technical notes or narrative reviews. Results Of 58 articles, five were included in this study, of which three and two had level III and IV evidence, respectively, four were comparative studies, and one was a case series. Visual analogue scales were used in four of the five studies, all showing improvement in pain assessment from 5.87 preoperatively to 1.02 postoperatively. All five studies showed significant improvement on each functional outcome score at the final follow-up. The retear rate for all studies was 10.97% (27 of 246). Conclusion High-grade bursal side partial-thickness rotator cuff–tear repair gave satisfactory results in terms of pain scores, range of motion, and functional outcomes. The retear rate was still considerably high (10.9%), necessitating better understanding of the basic science, such as molecular mechanisms during adaptation, to improve the surgical technique.

Abstract
Colorectal cancer (CRC), is the second cause of cancer-related deaths worldwide is one of the most prevalent types of cancers. Conventional treatment continues to rely on surgery, chemotherapy, and radiotherapy, but for advanced cases, adjuvant chemotherapy remains the main approach for improving surgical outcomes and lower the disease recurrence probability. Chemotherapy-induced gastrointestinal (GI) toxicity is the main dose-limiting factor for many chemotherapeutic regimens, including 5-FU, and one of the biggest oncological challenges. Up to 40% of the patients receiving 5-FU get mucositis, 10-15% of which develop severe symptoms. In this context, our study aimed to develop a bioinspired nanosized drug delivery system as a strategy to reduce 5-FU associated side effects, such as GI mucositis. To this end, SF-based nanoparticles were prepared and characterized in terms of size and morphology, as well as in terms of in vitro antitumoral activity on a biomimetic colorectal cancer model by investigation of apoptosis, DNA fragmentation, and release of reactive oxygen species. Additionally, the capacity of the SF-based nanocarriers to offer intestinal protection against 5-FU-induced GI mucositis was evaluated in vivo using a mouse model that mimics the chemotherapy-associated gut mucositis occurring in colorectal cancer. Our studies show that silk fibroin nanoparticles efficiently deliver 5-FU to tumor cells in vitro while protecting against drug-induced GI mucositis in a mouse model.

Abstract
Diabetic foot is among the most common complications of patients with diabetes. One of the known causes of foot ulceration is ankle equinus, which increases the pressure on the plantar surface during ambulation. Conversely, equinus contracture can be caused by a complicated wound, and it may be due to prolonged immobilization. In this paper, we reviewed the pathogenesis of both conditions and their clinical considerations. Poor glycemic control in patients with diabetes may result in angiopathy and neuropathy as an underlying condition. An ulcer can be precipitated by an injury, improper foot care, or increased biomechanical loading as seen in elevated plantar pressure following equinus contracture. Equinus contracture may be a direct effect of hyperglycemia or can arise in combination with another pathway, for example, involving the activation of transforming growth factor β. Static positioning resulting from any prior foot wound may develop fibrotic changes leading to contracture. Wound healing promoting factors can also result in overhealing outcomes such as hypertrophic scarring and fibrosis. The body’s repair mechanism during the healing cascade activates repair cells and myofibroblasts, which also serve as the main producers and organizers of the extracellular matrix. Considering this intricate pathogenesis, appropriate interventions are essential for breaking the vicious cycle that may disturb wound healing.

Abstract
The key to the success of cervical cancer control programs is screening followed by adequate treatment. The socio-economic status gap and the low level of education lead to limited awareness and understanding of women of childbearing age. Increasing the capacity of knowledge of women of childbearing age through health education either directly or indirectly is important. Therefore, there is need to develop health education by utilizing the rapidly growing media today such as through the application of cross platform messages on smartphones. This study aims to analyze the effect of the application of health education on detection of cervical cancer through the application of cross-platform messages to increase knowledge and attitude of Women in Childbearing Age. A quasi-experimental research of pre-posttest design with control groups conducted consisting of 72 subjects of Women in Childbearing Age. Fogg's Behavior Model was the conceptual framework that guided the development of the cross-platform messaging intervention. A series of checklist from expert panel conducted to inform the development of the cross-platform messaging intervention. The messages are delivered for a 7-day period in the morning. Data collection using a checklist instrument. Univariable analysis through Rasch and bivariable modeling using numerical categorical comparative test, difference using T test. Findings revealed a significant increase in participants’ knowledge and attitude of cervical cancer screening. Women of Childbearing Age whose health education through cross-platform application has a 3.5 times probability of knowledge and good attitude compared to women of childbearing age who are not getting health education through cross-platform applications. Health education through cross-platform messaging services can be a cheap and effective method to improve the knowledge and attitude of women of childbearing age, as well as reaching individuals who have never done early detection of cervical cancer.

Abstract
Actively proliferating cancer cells require sufficient amount of NADH and NADPH for biogenesis and to protect cells from the detrimental effect of reactive oxygen species. As both normal and cancer cells share the same NAD biosynthetic and metabolic pathways, selectively lowering levels of NAD(H) and NADPH would be a promising strategy for cancer treatment. Targeting nicotinamide phosphoribosyltransferase (NAMPT), a rate limiting enzyme of the NAD salvage pathway, affects the NAD and NADPH pool. Similarly, lowering NADPH by mutant isocitrate dehydrogenase 1/2 (IDH1/2) which produces D-2-hydroxyglutarate (D-2HG), an oncometabolite that downregulates nicotinate phosphoribosyltransferase (NAPRT) via hypermethylation on the promoter region, results in epigenetic regulation. NADPH is used to generate D-2HG, and is also needed to protect dihydrofolate reductase, the target for methotrexate, from degradation. NAD and NADPH pools in various cancer types are regulated by several metabolic enzymes, including methylenetetrahydrofolate dehydrogenase, serine hydroxymethyltransferase, and aldehyde dehydrogenase. Thus, targeting NAD and NADPH synthesis under special circumstances is a novel approach to treat some cancers. This article provides the rationale for targeting the key enzymes that maintain the NAD/NADPH pool, and reviews preclinical studies of targeting these enzymes in cancers.

Abstract
Abstract: The distal end radius and ulna is an integral part of the wrist joint and preservation of its normal anatomy is essential for the mobility of the wrist. The most common cause of residual wrist disability after distal end radius fractures is the disruption of distal radioulnar joint (DRUJ). Early recognition and management in the acute stage aim at the anatomic reconstruction of the DRUJ in an effort to reduce incidence of chronic pain and loss of wrist motion. The purpose of this study is to identify the prevalence of accompanying DRUJ in distal end radius fracture cases, highlighting its significance in occurance. This was a retrospective study with an analytic descriptive method and data from January 2013-December 2015 taken from medical records of Dr. Hasan Sadikin Hospital. From research, we found 74 cases of distal end radius fracture. The most common injured wrist were dominant hand as 46 cases (62,2%), and non-dominant hand as 28 cases (37,8%). From all data, DRUJ disruption were marked as 37 cases (50%). Extraarticular fracture with concomitant DRUJ disruption were marked in 3 cases (8,1%) and in intraarticular involvement were 34 cases (91,9 %). From this study, we can conclude that half of the distal end radius fracture cases, especially intraarticular, were accompanied by DRUJ disruption. This should be an issue to be concerned by the physician when evaluating distal end radius fracture cases and to perform proper treatment.

Abstract
INTRODUCTION Hypospadias is one of the most common congenital anomalies of the penis. Previous studies reported mutation of the Wilms' tumor 1 (WT1) gene as a cause of hypospadias. The aim of this study is to describe the WT1 mutation spectrum and polymorphism in hypospadias patients in Indonesia. MATERIAL AND METHODS DNA was isolated from 74 hypospadias patients at the Division of Pediatric Surgery, Department of Surgery Hasan Sadikin Hospital. All exons in the WT1 gene were amplified by a PCR method, followed by Sanger sequencing. Mutation analysis was performed using BioEdit software and in silico analysis using Mutation Taster, Polymorphism Phenotyping-2 (PolyPhen-2), and Sorting Intolerant from Tolerant (SIFT). RESULT DNA analysis results showed two types of heterozygous mutations in five subjects (Table), hence the frequency of WT1 mutations was 6.7% (10/148 allele). The first mutation was a missense mutation identified in twin boys. The second was a novel heterozygous alteration in the non-coding region nine bp upstream of exon 6 (c.366-9T>C), which was identified in three patients. One heterozygous polymorphism in the coding region of exon 7 (c.471A>G/rs16754) was identified in 10 subjects. This variant did not cause any change in amino acid products (silence polymorphism). Allele frequency for the G allele (mutant allele) and A allele (wild type) was 13.5% and 86.5%, respectively. DISCUSSION WT1 is one of the best known hypospadias genes. The WT1 gene is involved in male genital development in the early and late periods of sex determination, and hence is known as a long-term expression gene in genitalia development. Mutation analysis of WT1 in a Chinese population identified that the WT1 mutation frequency was 4.4%. The WT1 mutation frequency identified in the present study was higher, at 6.7%. Coincidentally, research subjects with p.R158H variants were monozygotic twin siblings with midshaft hypospadias accompanied by undescended testis in one and penoscrotal hypospadia with micropenis in the other. The incidence of familial hypospadias in male siblings suffering from hypospadias was reported to be 9.6% in a study conducted by Sorensen et al. Moreover, in the present study polymorphism c.471A>G(rs16754) at exon 7 was identified heterozygously in 10 research subjects (minor allele frequency 13.5%). CONCLUSION WT1 mutations were identified in only a few cases of hypospadias and most of these were syndromic. This result implies that mutation of WT1 is not a common cause of hypospadias in the Indonesian population.

Abstract
Doxorubicin (DOX) is one of the most effective chemotherapeutic agents, but its efficiency is seriously limited by the risk of developing cardiomyopathy. The most recognized cardiotoxic effect is left ventricular (LF) dysfunction, but MRI and echocardiography data demonstrated significant right ventricle (RV) function impairment. In order to clarify this aspect, the present study investigated the potential of DOX to induce acute RV cardiotoxicity at the same time as LV impairment. Rats were intraperitoneally (i.p.) injected with a single dose of 15 mg/kg DOX. DOX-treated rats were characterized by decreased body and heart weights, elevated levels of creatine kinase (CK-MB) and lactate dehydrogenase (LDH) activities compared to controls. Biochemical analyses on RV tissue revealed that the level of malondialdehyde (MDA) was significant increased (p<0.05) and activities of catalase (CAT), glutathione reductase (GR), glutathione peroxidase (GPX) antioxidant enzymes were decreased by 13%, 27% and 18%, respectively, compared to control. Histopathogical and electron microscopic studies revealed DOX-induced damage in both ventricles and an increase of interstitial collagen fibers compared to controls (p<0.001), whereas immunohistochemical analysis showed weak and irregular desmin expression. Furthermore, mitochondrion-induced apoptotic pathways were also activated in both ventricles, as reflected by the up-regulation of Bax/Bcl-2 mRNA expression ratio (p<0.001) and increase of Bax and caspase-3 protein expression, as well as by the significant elevation of TUNEL positive nuclei, compared to controls (p<0.001). The results showed that DOX exerted RV toxic effects at the same time as those reported in the LV, which might be mediated through the mitochondrial-dependent apoptosis.

Abstract
BACKGROUND AND OBJECTIVES Infant birth weight might be partly contributed to by maternal nutritional status at birth and maternal nutrition during pregnancy. The objective of this study was to analyze intergenerational maternal birth weight, maternal BMI, weight change during pregnancy, and maternal body composition (FM, FFM, and TBW) changes during pregnancy. METHODS AND STUDY DESIGN We analyzed the associations between the maternal birth weight and body composition of 94 women and infant birth weight by using multiple regression adjusted for socioeconomic and reproductive history. RESULTS All associations with infant birth weight were positive. The association between infant birth weight and maternal birth weight was 0.28 (95% CI: 0.02-0.54); that for the association between infant birth weight and maternal body weight in the first, second, and third trimesters was 15.1 (95% CI: 4.92-25.3), 13.7 (95% CI: 2.78-24.6), and 16.1 (95% CI: 5.22-27.0), respectively. The association between infant birth weight and fat mass in the second and third trimesters were 18.4 (95% CI: 3.38-33.5) and 16.1 (95% CI: 5.23-27.0), respectively, and those for the association between infant birth weight and fat-free mass in the first and third trimesters were 33.6 (6.38, 60.9) and 34.8 (95% CI: 3.47-66.1), respectively. CONCLUSIONS This study confirms previous findings that maternal birth weight and body composition during pregnancy are associated with infant birth weight.

Abstract
Chrysin (CHR) is a natural flavonoid and is present in high concentration in honey, propolis and many plant extracts. The aim of the present study was to evaluate the effects of CHR to reduce cardiomyocyte apoptosis and loss of intermediate filaments in a mouse model of mitoxantrone cardiotoxicity. Morphology of the cardiomyocytes was determined by optic and transmission electron microscopy and biochemistry methods. The expression of Bcl-2, Bax and Caspase-3 were assessed by immunofluorecence. Tunel assay was used to assess apoptosis in cardiomyocytes. In addition, the distribution of desmin protein was evaluated using immunohistochemistry. Our results show that MTX treatment significantly increased serum levels of creatine kinase isoenzyme (CK-MB), indicator of cardiac injury and withdrawn under CHR protection. Expression levels of Bcl-2 decreased, while those of Bax and caspase-3 increased following MTX treatment. 50 mg/kg of daily CHR intake reduced Bax and caspase-3 immunopositivity and restored Bcl-2 levels to a value comparable to the control. TUNEL (+) cardiomyocyte nuclei of MTX group showed typical signs of apoptosis which almost completely disappeared in response to 50 mg/kg CHR treatment. In parallel, an irregular distribution and a weak expression of desmin is associated with MTX induced cardiotoxic effects which was also restored by CHR treatment. In conclusion chrysin inhibits MTX-triggered cardiomyocyte apoptosis via multiple pathways, including decrease of the Bax/Bcl-2 ratio and caspase-3 expression along with preservation of the desmin disarray.

Abstract
A new phoswich detector is being developed at the Crump Institute, aiming to provide improvements in sensitivity, and spatial resolution for PET. The detector configuration is comprised of two layers of pixelated scintillator crystal arrays, a glass light guide and a light detector. The annihilation photon entrance (top) layer is a 48 × 48 array of 1.01 × 1.01 × 7 mm3 LYSO crystals. The bottom layer is a 32 × 32 array of 1.55 × 1.55 × 9 mm3 BGO crystals. A tapered, multiple-element glass lightguide is used to couple the exit end of the BGO crystal array (52 × 52 mm2) to the photosensitive area of the Position Sensitive Photomultiplier Tube (46 × 46 mm2), allowing the creation of flat panel detectors without gaps between the detector modules. Both simulations and measurements were performed to evaluate the characteristics and benefits of the proposed design. The GATE Monte Carlo simulation indicated that the total fraction of the cross layer crystal scatter (CLCS) events in singles detection mode for this detector geometry is 13.2%. The large majority of these CLCS events (10.1% out of 13.2%) deposit most of their energy in a scintillator layer other than the layer of first interaction. Identification of those CLCS events for rejection or correction may lead to improvements in data quality and imaging performance. Physical measurements with the prototype detector showed that the LYSO, BGO and CLCS events were successfully identified using the delayed charge integration (DCI) technique, with more than 95% of the LYSO and BGO crystal elements clearly resolved. The measured peak-to-valley ratios (PVR) in the flood histograms were 3.5 for LYSO and 2.0 for BGO. For LYSO, the energy resolution ranged from 9.7% to 37.0% full width at half maximum (FWHM), with a mean of 13.4 ± 4.8%. For BGO the energy resolution ranged from 16.0% to 33.9% FWHM, with a mean of 18.6 ± 3.2%. In conclusion, these results demonstrate that the proposed detector is feasible and can potentially lead to a high spatial resolution, high sensitivity and DOI PET system.

Abstract
UNLABELLED In the present study, we analysed the association between the incidence of tuberculous spondylitis with the Natural Resistance Associated Macrophage Protein 1 (NRAMP1, also known as Solute Carrier Family 11a member1) polymorphism by studying the genetic segregation of this polymorphism and the incidence of the disease among members of the West Javanese population undergoing surgery for tuberculous spondylitis at our institution. We compared the distribution of NRAMP1 polymorphism at two specific sites, namely D543N, and 3'UTR, among subjects with pulmonary tuberculosis and tuberculous spondylitis. We found no significant differences in distribution of polymorphism between the two groups, or between pulmonary tuberculosis and tuberculous spondylitis compared to healthy subjects. However, a pattern emerged in that polymorphisms at the two sites seemed to be protective against development of tuberculous spondylitis in our study population. We concluded that in the West Javanese population, there is no association between NRAMP1 polymorphism with the propensity for development of pulmonary tuberculosis or tuberculous spondylitis. In fact, NRAMP1 may provide protection against the development of tuberculous spondylitis. KEY WORDS tuberculous spondylitis, NRAMP1, polymorphism.

Abstract
Epigenetic marks are fundamental to normal development, but little is known about signals that dictate their placement. Insights have been provided by studies of imprinted loci in mammals, where monoallelic expression is epigenetically controlled. Imprinted expression is regulated by DNA methylation programmed during gametogenesis in a sex-specific manner and maintained after fertilization. At Rasgrf1 in mouse, paternal-specific DNA methylation on a differential methylation domain (DMD) requires downstream tandem repeats. The DMD and repeats constitute a binary switch regulating paternal-specific expression. Here, we define sequences sufficient for imprinted methylation using two transgenic mouse lines: One carries the entire Rasgrf1 cluster (RC); the second carries only the DMD and repeats (DR) from Rasgrf1. The RC transgene recapitulated all aspects of imprinting seen at the endogenous locus. DR underwent proper DNA methylation establishment in sperm and erasure in oocytes, indicating the DMD and repeats are sufficient to program imprinted DNA methylation in germlines. Both transgenes produce a DMD-spanning pit-RNA, previously shown to be necessary for imprinted DNA methylation at the endogenous locus. We show that when pit-RNA expression is controlled by the repeats, it regulates DNA methylation in cis only and not in trans. Interestingly, pedigree history dictated whether established DR methylation patterns were maintained after fertilization. When DR was paternally transmitted followed by maternal transmission, the unmethylated state that was properly established in the female germlines could not be maintained. This provides a model for transgenerational epigenetic inheritance in mice.

Abstract
ABSTRACTThick coatings of Y-Ba-Cu-oxide superconductors have been prepared by plasma spray processing. This paper reports a number of the important properties of coatings sprayed at two different power levels. The microstructure, porosity, and chemical composition of the coatings were studied in their as-sprayed and annealed states. Critical current and magnetic susceptibility measurements were made on the annealed coatings. X-ray diffraction was used to identify non-superconducting phases present in the coatings and to determine the superconducting phase's lattice constants.

Abstract
AbstractThermal spray technologies provide a method for depositing high temperature intermetallics. Deposits of Shape Memory Effect NiTi were produced by Electric-Arc Spraying (EAS) of NiTi wire, Vacuum Plasma Spraying (VPS) of NiTi powder, and codeposition of Ni and Ti using VPS. NiTi deposits displayed shape memory effect properties, which are highly sensitive to processing conditions. They were found to also exhibit superior cavitation-erosion resistance. Under identical cavitation erosion conditions, weight losses of 0.41, 1.65 amd 7.71 mg were found VPS, arc-sprayed and blended Ni-Ti deposits respectively. Minimal amounts of NiTi was formed from co-spraying both Ni and Ti powders onto steel substrates.

Abstract
Thermal Spray is a directed spray process, in which material, generally in molten form, is accelerated to high velocities, impinging upon a substrate, where a dense and strongly adhered deposit is rapidly built. In the case of ceramic deposits, it is necessary to bring the particles to well above the melting point, which is achieved by either a combustion flame or a thermal plasma arc. The deposit microstructure and, thus, properties, aside from being dependent on the spray material, rely on the processing parameters, which are numerous and complex. In recent years, through concerted, integrated efforts of the Center for Thermal Spray Research at the State University of New York at Stony Brook and others, significant fundamental understanding of the process has been achieved, allowing for an enhanced control of the process.

Abstract
At the imprinted Rasgrf1 locus in mouse, a cis-acting sequence controls DNA methylation at a differentially methylated domain (DMD). While characterizing epigenetic marks over the DMD, we observed that DNA and H3K27 trimethylation are mutually exclusive, with DNA and H3K27 methylation limited to the paternal and maternal sequences, respectively. The mutual exclusion arises because one mark prevents placement of the other. We demonstrated this in five ways: using 5-azacytidine treatments and mutations at the endogenous locus that disrupt DNA methylation; using a transgenic model in which the maternal DMD inappropriately acquired DNA methylation; and by analyzing materials from cells and embryos lacking SUZ12 and YY1. SUZ12 is part of the PRC2 complex, which is needed for placing H3K27me3, and YY1 recruits PRC2 to sites of action. Results from each experimental system consistently demonstrated antagonism between H3K27me3 and DNA methylation. When DNA methylation was lost, H3K27me3 encroached into sites where it had not been before; inappropriate acquisition of DNA methylation excluded normal placement of H3K27me3, and loss of factors needed for H3K27 methylation enabled DNA methylation to appear where it had been excluded. These data reveal the previously unknown antagonism between H3K27 and DNA methylation and identify a means by which epigenetic states may change during disease and development. Methylation of DNA and histones exert profound and inherited effects on gene expression. These occur without changes to the underlying DNA sequence and are considered epigenetic effects. Disrupting epigenetic states can cause developmental abnormalities and cancer. Very little is known about how locations in the mammalian genome are chosen to receive these chemical modifications, or how their placement is regulated. We have identified a DNA sequence that acts as a methylation programmer at the Rasgrf1 locus in mice. It is required for methylation of nearby DNA sequences and can also influence the levels of local histone methylation. The methylation programmer has different effects on paternally and maternally derived chromosomes, directing DNA methylation on the paternal allele and histone H3 lysine 27 trimethylation on the maternal allele. These two methylation marks are not only mutually exclusive; they are also mutually antagonizing, whereby one blocks the placement of the other. Manipulations that cause aberrant changes in the levels of one of these marks had the opposite effect on the other mark. These observations identify novel mechanisms that specify epigenetic states in vivo and provide a framework for understanding how pathological epigenetic changes can arise, including those emerging at tumor suppressors during carcinogenesis.

Abstract
OBJECTIVES Obstetric trauma to the puborectal muscle seems to be an important cause of pelvic floor dysfunction in women. Due to the complicated three-dimensional (3D) arrangement of the pelvic structures, two-dimensional images are not sufficient to demonstrate its relationships in a complex fashion. Thus, we aimed to create a 3D computer model to visualize the normal female pelvic floor anatomy and to compare this with the anatomy after bilateral avulsion of the puborectal muscle following delivery. METHODS We created two 3D computer models of the female pelvic floor, one of a healthy nulliparous woman and the other of a woman with bilateral puborectal muscle avulsion after vaginal delivery. The data for the models were obtained from magnetic resonance imaging examinations and the following structures were depicted: pelvic bones, puborectal muscle, internal obturator muscle, urethra, urinary bladder, vagina and rectum. The models were compared. RESULTS The models allowed us to demonstrate in three dimensions changes in the puborectal muscle after avulsion. Its relations to the bone, internal obturator muscle, perineal membrane and the deep part of the external anal sphincter were modeled and differences from the normal non-injured anatomy were demonstrated. Avulsion altered the support to the whole endopelvic fascia and destabilized both the anterior and the posterior vaginal walls. CONCLUSIONS The use of 3D technology including modeling allows for the acquisition of new knowledge and aids in the understanding of both normal and pathological pelvic anatomy.

Abstract
OBJECTIVE Analysis of pregnancy related complications in infertile patient after laparoscopic myometomy (LM). DESIGN Retrospective analytic study. SETTING Institute for the Care of Mother and Child, Prague; Institute for Postgraduate Medical Education, Prague. METHODS The study group were infertile patients referred to our department with the finding of uterine fibroid(s). In all patients LM was the method of choice. Thorough information and results from all infertile patient after LM were assessed and analysed with 18 months follow-up after surgery. RESULTS The aim of our study was to evaluate pregnancy rate and the possible risks during pregnancy and delivery following LM. We analysed 69 patients after LM. Mean size of a fibroid was 3.3 cm and the number of removed fibroids in one patient was 1.8. The conception rate after LM was 56.5%. We didn't observe any increased incidence of fetomaternal morbidity or severe pregnancy and labour related complications. There was no uterine rupture after LM in our group. The cesarean section was rate 44.8%. CONCLUSIONS The impact of fiborids on infertility is still controversial. LM in infertile patient is one of the most common surgical procedure. The appropriate surgical management of uterine scar is mandatory. This operation must be performed by skilled reproductive surgeon. Thorough information to the patient before and after LM is necessary. The pregnancy following LM is at high risk with increased caesarean section rate.

Abstract
OBJECTIVE Evaluation of the influence of vaginal childbirth on the integrity of the puborectalis muscle with the help of real-time 3D ultrasound. DESIGN Prospective pilot study. SETTING Institute for Care for Mother and Child, Prague, Czech Republic. MATERIAL AND METHODS We examined 20 primigravid women in the third trimester and on the third day after vaginal delivery. The transperineal 3D ultrasound examination was performed and the data were evaluated afterwards in the 4D view software. The VCI (Volume Contrast Imaging) mode with slice thickness 3 millimeters was used for analysis. We evaluated the integrity of the puborectalis muscle on both sides, the quality of the images and the presence of hematomas. RESULTS The examination before delivery did not show any abnormal anatomy of the examined region. We found four (20%) unilateral defects and one (5%) bilateral puborectalis avulsion after the delivery. The bilateral defect was after the forceps delivery, the other defects occurred after normal uncomplicated vaginal deliveries, where only left mediolateral episiotomy was performed and the birth weight did not exceed 3700 g. In our series, 25% of women suffered an injury of a major muscle of pelvic floor. No defect was diagnosed during the delivery and did not show any connection with the episiotomy. CONCLUSIONS 3D ultrasound can detect major birth trauma to the puborectalis muscle. The puborectalis muscle avulsion is usually not recognized during the delivery and does not cause immediate problem to the patient.

Abstract
Imprinted methylation of the paternal Rasgrf1 allele in mice occurs at a differentially methylated domain (DMD) 30 kbp 5' of the promoter. A repeated sequence 3' of the DMD regulates imprinted methylation, which is required for imprinted expression. Here we identify the mechanism by which methylation controls imprinting. The DMD is an enhancer blocker that binds CTCF in a methylation-sensitive manner. CTCF bound to the unmethylated maternal allele silences expression. CTCF binding to the paternal allele is prevented by repeat-mediated methylation, allowing expression. Optimal in vitro enhancer-blocking activity requires CTCF binding sites. The enhancer blocker can be bypassed in vivo and imprinting abolished by placing an extra enhancer proximal to the promoter. Together, the repeats and the DMD constitute a binary switch that regulates Rasgrf1 imprinting.

Abstract
OBJECTIVE To evaluate our clinical results and reproductive outcome after laparoscopic surgery for ovarian endometriosis in infertile women. DESIGN Analytic retrospective study. SETTING Institute for the Mother and Child Care, Prague, Institute for Postgraduate Medical Education, Prague, Czech republic. RESULTS Surgical treatment in infertile patient should be conservative as much as possible. Laparoscopic surgery has the potential to achieve very good results in the treatment of endometriomas. Surgical treatment of the endometriotic cyst is still controversial. There are several surgical options in the treatment of an endometrioma. In our department we use laparoscopic stripping of the capsule. During 2000-2003 we operated on 70 infertile women with an endometrioma. The average age of the patients was 30.5 year and the average diameter of all endometriomas was 5.0 cm. The cumulative delivery rate after surgery was 55.7 % (n = 39). CONCLUSION We present our clinical results after laparoscopic conservative surgery for ovarian endometriosis. The achieved pregnancy rate in our group is comparable to the results published in other studies.

Abstract
OBJECTIVE Case report of a successful treatment of ovarian endometriosis by laparoscopic ovariopexy in infertile women. DESIGN Case report. SETTING Institute for the Care of Mother and Child, Prague, Institute for Postgraduate Medical Education, Prague. RESULTS Conservative treatment of ovarian endometriosis is often complicated by postoperative periadnexal adhaesions which may result in pelvic pain or ongoing infertility. Temporary laparoscopic ovarian suspension--ovariopexis is a very effective method in postoperative adhaesion prevention and in the treatment of ovarian endometriosis in infertile patient. We observed successful cases of laparoscopic treatment of ovarian endometriosis. CONCLUSION Laparoscopic ovariopexis is a simple and effective method for treatment of ovarian endometriosis and prevention of extensive periadnexal adhaesions.

Abstract
In mammals, imprinted genes have parent-of-origin-specific patterns of DNA methylation that cause allele-specific expression. At Rasgrf1 (encoding RAS protein-specific guanine nucleotide-releasing factor 1), a repeated DNA element is needed to establish methylation and expression of the active paternal allele. At Igf2r (encoding insulin-like growth factor 2 receptor), a sequence called region 2 is needed for methylation of the active maternal allele. Here we show that replacing the Rasgrf1 repeats on the paternal allele with region 2 allows both methylation and expression of the paternal copy of Rasgrf1, indicating that sequences that control methylation can function ectopically. Paternal transmission of the mutated allele also induced methylation and expression in trans of the normally unmethylated and silent wild-type maternal allele. Once activated, the wild-type maternal Rasgrf1 allele maintained its activated state in the next generation independently of the paternal allele. These results recapitulate in mice several features in common with paramutation described in plants.

Abstract
In mammals, DNA is methylated at cytosines within CpG dinucleotides. Properly regulated methylation is crucial for normal development. Inappropriate methylation may contribute to tumorigenesis by silencing tumor-suppressor genes or by activating growth-stimulating genes. Although many genes have been identified that acquire methylation and whose expression is methylation-sensitive, little is known about how DNA methylation is controlled. We have identified a DNA sequence that regulates establishment of DNA methylation in the male germ line at Rasgrf1. In mice, the imprinted Rasgrf1 locus is methylated on the paternal allele within a differentially methylated domain (DMD) 30 kbp 5' of the promoter. Expression is exclusively from the paternal allele in neonatal brain. Methylation is regulated by a repeated sequence, consisting of a 41-mer repeated 40 times, found immediately 3' of the DMD. This sequence is present in organisms in which Rasgrf1 is imprinted. In addition, DMD methylation is required for imprinted Rasgrf1 expression. Together the DMD and repeat element constitute a binary switch that regulates imprinting at the locus.
