A study published in the Journal of Biomedical Science finds that diabetic cataract starts before hyperglycemia, thus challenging the prevailing paradigm that glucose initiates or is necessary for initiation of cataract pathogenesis.
]. Pigmented Long-Evans rats were purchased . Animals were maintained in a temperature-controlled environment with a 12 h dark/light cycle and provided access to standard chow and water ad libitum.The surgical microscope Pentero 900 was used to visualize the pathological changes in the lenses of live NGRs.
The following antibodies were used: goat anti-E-Cadherin , rabbit anti-MAGP1 , rabbit anti-CD45 , rabbit anti-CD68 and secondary antibodies . An in situ cell death detection kit was used for the TUNEL assay.To investigate trafficking of immune cells to the lens, we developed an in situ anterior half-globe microscopy technique. Eyes were snap frozen, OCT-embedded, and gradually cut from back toward the front to reach the height of the ciliary bodies, using a cryostat .

Eccentric exercise is more effective than other exercises in the treatment of mid-portion Achilles tendinopathy: systematic review and meta-analysis - BMC Sports Science, Medicine and RehabilitationAchilles tendinopathy (AT) is one of the most frequent overuse injuries in the ankle. The evidence base for its conservative management AT continues to evolve, but there is still a gap in the evidence for the efficacy of any modality of treatment in high-quality studies. This systematic review and meta-analysis investigated the efficacy of EE in improving pain and function in adult patients with mid-portion Achilles tendinopathy compared to other forms of exercise. A search was performed in PubMed, BIREME, SportDiscus, Cinahl, Web of Science and PEDro, in November 2022. The methodological quality was evaluated using the Risk of Bias 2 tool (RoB2) of the Cochrane collaboration, and the meta-analysis was performed using the Review Manager 5.1 program. 2024 articles were identified and eight fulfilled the inclusion criteria. RoB2 presented a final score with 62.5% of the studies presented “some concerns”, and 37.5% (five and three articles, respectively) presenting “high risk” of bias. EE was effective for the managment of AT. The only variable for which a meta-analysis was possible was pain (five articles), analysed with the visual analogue scale/numerical visual scale. The mean difference (MD) in treatment effect using EE was − 1.21 (− 2.72 to − 0.30) with a 95% of confidence interval (CI), thus identifying a significant positive effect for the improvement of pain in patients with AT in whom EE was used. EE is effective in the management of AT. The meta-analysis shows the need for appropriately powered randomized controlled trials with better design, the use of standard outcome measures and well-planned protocols for conservative management of AT.Level of evidence: Level 1.Registration: CRD42018118016.
