Chemotherapeutic agents result in the loss of growing follicles, which can manifest as amenorrhoea. Alkylating chemotherapy (AC) is known to be more gonadotoxic than non-alkylating chemotherapy (NAC). Anti-Mullerian Hormone (AMH), an indirect marker of ovarian reserve, and age have been investigated as predictors of ovarian function after chemotherapy, however little is known about the time to return of menses.

The polymorphic CAG locus in exon 1 of the gene is associated with several diseases, including spinal and bulbar muscular atrophy (SBMA), prostate cancer, and male infertility. This study evaluated the CAG locus in 9000 infertile Russian men and 286 fertile men (control group).

- Pathogenic variants in a specific gene are found to be the main cause of both non-syndromic and syndromic forms of inherited retinitis pigmentosa (RP), which leads to retinal degeneration and hearing loss.
- A study analyzed genetic data from 2415 patients in Russia to identify various pathogenic variants and their frequency in those with isolated RP versus those with the syndromic form.
- The research revealed key differences in genetic variants between the two groups, highlighting the need for better understanding of genotype-phenotype relationships to improve disease management and treatment options like cochlear implants.
Unlabelled: Rehabilitation of children with fractures of the upper wall of the maxillary sinus remains relevant due to the need for a balanced approach to treatment, which would take into account both the features of traumatic injuries in children and the specifics of their age development. The article describes a technique for combined (endoscopic transnasal and transconjunctival) surgical treatment of children with fractures of the upper wall of the maxillary sinus using a sinus balloon catheter.
Objective: To study the effectiveness and safety of the functional method of treating fractures of the upper wall of the maxillary sinus using endoscopic sinus surgery and a sinus balloon catheter.
p-NiO/n-GaO heterojunction (HJ) diodes exhibit much larger changes in their properties upon 1.1 MeV proton irradiation than Schottky diodes (SDs) prepared on the same material. In p-NiO/GaO HJ diodes, the narrow region adjacent to the HJ boundary is found to contain a high density of relatively deep centers with levels near E-0.
