MicroRNAs are involved in the regulation of the autophagy and proliferation in several diseases. This study aims to verify the role of miR-25-3p in the proliferation and autophagy of renal cells in polycystic kidney disease (PKD). We found that kidney to body weight and blood urea content were increased in PKD mice. Cystic dilations were increased in kidney tissue from PKD mice, and autophagy-related protein ULK1 and the ratio of LC3-II/LC3-I were decreased, indicating autophagy was inhibited in PKD mice. In addition, miR-25-3p was upregulated in PKD mice, and inhibition of miR-25-3p decreased cystic dilations in kidney tissues, increased ULK1 expression and the ratio of LC3-II/LC3-I, indicating inhibition of miR-25-3p enhanced the autophagy in PKD. Besides, inhibition of miR-25-3p suppressed the proliferation of renal cells and downregulated E2F-1 and PCNA expressions. Importantly, miR-25-3p targetedly suppressed ATG14 expression in PKD cells. read more Finally, silencing ATG14 abolished the inhibition effect of miR-25-3p inhibitor on renal cell proliferation, and reversed the inhibition effect of miR-25-3p inhibitor on E2F-1 and PCNA expressions in in vitro and in vivo experiments, which suggested that ATG14 was involved in the regulation of miR-25-3p-mediated kidney cell proliferation. Therefore, inhibition of miR-25-3p promoted cell autophagy and suppressed cell proliferation in PKD mice through regulating ATG14.Due to specific habitat preferences and behavioural limitations, black francolin is not uniformly distributed across the northwestern Himalayan landscape, rather is confined to certain land mosaic. The habitable zones are further reduced due to several manmade threats as logging and forest fire leading to sparse distribution. Overall 54 samples were used for partial sequence analysis of mitochondrial control region. A well evident divergence pattern was observed as individuals collected from low altitude, terrai region significantly distanced from high altitude sampled individuals. Also, the individuals at lower elevation sites exhibited higher genetic diversity in comparison to the samples collected at higher elevations. This indicates that patchy distribution and low dispersal rate have resulted in fine-scale patterns of genetic diversity among the black francolin population. Further, habitat loss and forest fragmentation could lead to more small and isolated populations that could suffer from reduced genetic diversity and may be higher extinction rates.Background Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder characterized by benign hamartomas occurring in multiple organ systems including the brain, kidneys, heart, lungs, liver, skin, and the eyes. Typical retinal findings associated with TSC include astrocytic hamartoma and achromic patch. While rare cases of cataract occurring in the setting of TSC have been reported, this is the first analysis of a large series of individuals with TSC that aims to quantify the frequency of this finding and to describe its clinical and genetic associations.Materials and Methods This is a retrospective chart review of 244 patients from the Herscot Center for Tuberous Sclerosis Complex at the Massachusetts General Hospital who underwent complete ophthalmic examination. We describe the clinical and genetic findings in five individuals with TSC and juvenile cataract.Results Four of five cases (80%) were unilateral. The cataract was described as having an anterior subcapsular component in 3 of 5 cases (60%). Three individuals (60%) underwent lensectomy with intraocular lens (IOL) implant and two individuals (40%) were observed. Genetic testing revealed a known disease-causing mutation in TSC2 in 100% of cases.Conclusions Recent evidence suggests that mTOR signaling may play a role in cataract formation which could explain the relatively high incidence of juvenile cataract in this population. Juvenile cataract is a potentially under-recognized ocular manifestation of TSC.Purpose We describe a novel surgical approach for bilateral orbital roof decompression using a frontal osteoplastic flap without frontal sinus obliteration. This technique utilizes a combined external and endonasal endoscopic approach for wide exposure to the orbital roof bilaterally. We demonstrate this technique for the resection of a massive frontal fibrous dysplasia lesion in a healthy male with bilateral orbital roof involvement. The endonasal endoscopic portion of the technique includes a Draf III frontal sinusotomy (endoscopic modified Lothrop procedure) which precludes the need for frontal sinus obliteration, restores normal frontal sinus function, and allows for postoperative endoscopic surveillance.Methods Report of novel surgical technique with video demonstration.Results This technique for orbital roof decompression allows for removal of a frontal lesion, wide decompression of the bilateral orbital roof, and post-operative endonasal endoscopic surveillance of the cavity. The patient in whom we demonstrate this technique had complete resolution of his orbital symptoms and minimal residual fibrous dysplasia postoperatively.Conclusion Bilateral orbital roof decompression for frontal lesions can be performed safely and effectively with a frontal osteoplastic flap without frontal sinus obliteration, restoring normal orbital and sinus function.Objectives This study was conducted to assess the real-world safety and effectiveness of adalimumab in patients with juvenile idiopathic arthritis (JIA).Methods In this all-case, postmarketing surveillance study (NCT01412021) conducted in Japan, patients receiving adalimumab for JIA affecting multiple joints were observed for 24 weeks. The safety (adverse drug reactions [ADRs]/serious ADRs) and effectiveness (4-variable Disease Activity Score in 28 joints using erythrocyte sedimentation rate [DAS28-4/ESR] remission rate) were assessed.Results In the safety population (n = 356), 90.3% (65/72; weight, ≥15- less then 30 kg) of patients received adalimumab 20 mg every 2 weeks (q2w) and 98.3% (236/240; weight ≥30 kg) received 40 mg q2w. Incidence of ADRs and serious ADRs was 29.8% (106/356) and 3.4% (12/356), respectively. Incidence of ADRs was significantly higher in patients aged less then 15 years vs. ≥15 years (34.6% vs. 21.1%, p = .0072), those with comorbidities vs. without (38.3% vs. 25.7%, p = .0155), and those receiving dose less then 40 mg q2w vs.
