Abstracts:Fluoride is known to impair testicular functions and decrease testosterone levels, yet the underlying mechanisms remain inconclusive. The objective of this study is to investigate the roles of autophagy in fluoride-induced male reproductive toxicity by both in vivo and in vitro Leydig cell models. Using Transmission Electron Microscopy (TEM) and Monodansylcadaverine (MDC) staining, we observed increasing numbers of autophagosomes in testicular tissue, especially in Leydig cells of fluoride-exposed mice...

Three furan fused BODIPYs with a CF3 group on the meso-carbon are synthesized as near infrared (NIR) absorbing materi-als for vacuum processable organic solar cells (OSCs). The best single junction device reaches a short-circuit current (jsc) of 13.3 mA cm-2 and a power conversion efficiency (PCE) of 6.1%. These values are highly promising for an electron donor materi-al with an absorption onset beyond 900 nm. In a tandem solar cell (TSC) comprising a NIR BODIPY sub-cell and a matching "green" absorber sub-cell, complementary absorption is achieved, resulting in PCE of ~10%...

Hyperactivation of mammalian target of rapamycin complex 1 (mTORC1), caused by loss-of-function mutations in either the TSC1 or TSC2 gene, leads to the development of tuberous sclerosis complex (TSC), a benign tumor syndrome with multiple affected organs. mTORC1-mediated inhibition of AKT constrains the tumor progression of TSC, but the exact mechanisms remain unclear. Herein we showed that loss of TSC1 or TSC2 downregulation of platelet-derived growth factor receptor α (PDGFRα) expression was mediated by mTORC1...

This study was to investigate the feasibility of PGS combined with ChABC for repairing the transection of spinal cords (TSC) in rats. A thoracic 10 (T10) TSC model of rats was employed. The effects of PGS with ChABC on the morphology and histological structure of the spinal cords, Basso, Beattie, Bresnahan (BBB) scores, and the expression of GAP-43 and NF-200 were comparatively studied. The BBB scores indicated that all rats with TSC were paralyzed immediately after surgery and then recovered hind limb movement gradually, but did not fully recover until the end of week 12...

Angiomyomatous hamartoma of lymph nodes (AMH-LN) is an uncommon benign proliferation of smooth muscle, blood vessels, collagenous stroma and adipocytes, most commonly affecting inguinal LN. A similar constellation of cell types constitutes various members of the perivascular epithelioid cell tumor (PEComa) family, including lymphangioleiomyomatosis (LAM) which can involve LN in women. Because some LN-LAM patients have tuberous sclerosis complex (TSC) and/or other PEComa family lesions, it is clinically relevant to distinguish LN-LAM from AMH-LN...

Tuberous sclerosis complex (TSC) is a neurocutaneous autosomal dominant disorder that results from mutations within either the TSC1 gene or the TSC2 gene. Diagnosis is based on well-established clinical criteria or genetic criteria. Clinical features are highly variable and could be developing over the life. We present a case of TSC with a molecular test that identified a novel variant in TSC2 gene. It is a sporadic missense mutation which has not been previously reported in the literature. It is caused by premature termination of protein translation and results in the production of truncated and non-functional proteins...

Tuberous sclerosis complex (TSC) is a rare, genetic disease caused by loss-of-function mutations in either TSC1 or TSC2. Patients with TSC are neurologically characterized by the presence of abnormal brain structure, intractable epilepsy and TSC-associated neuropsychiatric disorders. Given the lack of effective long-term treatments for TSC, there is a need to gain greater insight into TSC-related pathophysiology and to identify and develop new treatments. In this work we show that homozygous tsc2(-/-) mutant zebrafish larvae, but not tsc2(+/-) and WT larvae, display enlarged brains, reduced locomotor behavior and epileptiform discharges at 7dpf...

Tuberous sclerosis complex (TSC) is an autosomal dominant multisystemic disorder caused by deregulation of the mTOR pathway, and represents one of the leading genetic causes of epilepsy. mTOR inhibitors (Sirolimus and Everolimus) are currently approved only for the treatment of growing subependymal giant cell astrocytomas, renal angiomyolipomas and lymphangioleiomyomatosis in TSC. However, preclinical and clinical evidence supports their potential role in effectively treating TSC-associated epilepsy, but no consensus on its use in seizures has been reached yet and there are few data on epilepsy outcome after the suspension of mTOR inhibitors treatment...

BACKGROUND: Tuberous sclerosis, also known as tuberous sclerosis complex (TSC), is a rare genetic condition that mainly causes hamartomas to develop in different parts of the body. TSC, an autosomal dominant trait with variable penetrance, can adversely affect maternal and fetal outcome. CASE PRESENTATION: In this paper, a case of maternal and fetal tuberous sclerosis having fetal cardiac rhabdomyoma detected in utero at 26 weeks was reported who subsequently had fetal demise at 31 weeks...

The ideal biomedical fiber/fabric materials can both promote the drug delivery properties and prevent microbial infection. Herein we present an innovation-based strategy for fabrication of biomedical cotton gauze which concomitantly displays antimicrobial and drug delivery performance properties. The innovative strategy involved three distinct steps: (1) Cationization of cotton gauze by reacting it with 3-chloro-2-hydroxypropyl trimethyl ammonium chloride [Quat-188] or anionization of cotton gauze through partial carboxymethylation...

BACKGROUND: For patients with tuberous sclerosis complex (TSC) with large subependymal giant cell astrocytoma (SEGA), direct surgical resection remains the standard treatment. Rapamycin/everolimus were seldom used in these patients because of increased intracranial pressure and possibility of sudden death. CASE DESCRIPTION: Three TSC patients with large intracranial SEGA received oral rapamycin (0.5 mg/day) or everolimus (2.5 mg/day) prior to surgery. Tumor resection was subsequently performed...

Organic-inorganic halide perovskites are promising photodetector materials due to their strong absorption, large carrier mobility, and easily tunable bandgap. Up to now, perovskite photodetectors are mainly based on polycrystalline thin films, which have some undesired properties such as large defective grain boundaries hindering the further improvement of the detector performance. Here, perovskite thin-single-crystal (TSC) photodetectors are fabricated with a vertical p-i-n structure. Due to the absence of grain-boundaries, the trap densities of TSCs are 10-100 folds lower than that of polycrystalline thin films...

BACKGROUND: Tuberous sclerosis complex (TSC) is a genetic disorder with high prevalence of associated autism spectrum disorder (ASD). Our primary objectives were to determine early predictors of autism risk to identify children with TSC in most need of early interventions. The Autism Observation Scale for Infants (AOSI) was evaluated as a measure of ASD-associated behaviors in infants with TSC at age 12 months and its ability to predict ASD at 24 months. METHODS: Children ages 0 to 36 months with TSC were enrolled in the TSC Autism Center of Excellence Research Network (TACERN), a multicenter, prospective observational study to identify biomarkers of ASD...

Atorvastatin is widely used to lower blood cholesterol and to reduce risk of cardiovascular disease-associated complications. Epidemiological investigations and preclinical studies suggest that statins such as atorvastatin have antitumor activity for various types of cancer. Tuberous sclerosis (TSC) is a tumor syndrome caused by TSC1 or TSC2 mutations that lead to aberrant activation of mTOR and tumor formation in multiple organs. Previous studies have demonstrated that atorvastatin selectively suppressed growth and proliferation of mouse Tsc2 null embryonic fibroblasts through inhibition of mTOR...

Parkinson's disease (PD) is the second most familiar, progressive and movement-related neurodegenerative disorder after Alzheimer disease. This study aimed to decipher the role of autophagy in cypermethrin-induced Parkinsonism, an animal model of PD. Indicators of autophagy [expression of beclin 1, autophagy-related protein 12 (Atg 12), unc-51 like autophagy activating kinase 1 (Ulk 1), p62 and lysosome-associated membrane protein 2 (LAMP 2) and conversion of microtubule-associated protein 1A/1B-light chain 3 (LC3) I to II], signalling cascade [phosphorylated (p) 5' adenosine monophosphate-activated protein kinase (p-AMPK), sirtuin 1 (Sirt 1), phosphorylated-mammalian target of rapamycin (p-mTOR), tuberous sclerosis complex 2 (TSC 2), p317Ulk 1 and p757Ulk 1 levels] and lysosome morphology were assessed in control and cypermethrin-treated rat model of PD...

Lymphangioleiomyomatosis (LAM) is a progressive destructive neoplasm of the lung associated with inactivating mutations in the TSC1 or TSC2 tumor suppressor genes. Cell or animal models that accurately reflect the pathology of LAM have been challenging to develop. Here we generated a robust human cell model of LAM by reprogramming TSC2 mutation-bearing fibroblasts from a patient with both Tuberous Sclerosis Complex (TSC) and LAM (TSC-LAM) into induced pluripotent stem cells (iPSCs), followed by selection of cells that resemble those found in LAM tumors by unbiased in vivo differentiation...
