The orthodontic management of mesial occlusion in patients with unilateral cleft lip and palate (UCLP) involves complex biomechanical considerations and treatment strategies that must be adapted to the unique anatomical and functional challenges associated with cleft conditions. Mesial occlusion, often associated with a prognathic skeletal pattern, is characterized by altered sagittal relationships between the maxilla and mandible, leading to compromised occlusal function and facial harmony. In individuals with UCLP, these discrepancies are frequently exacerbated by maxillary hypoplasia, dental arch asymmetry, and the long-term effects of surgical repair.

Histological variability of human tissues across age and sex refers to the structural, cellular, and functional differences that emerge over the lifespan and between biological sexes. This variability has important implications for understanding biological aging, differences in health outcomes, and susceptibility to disease among diverse populations. As aging progresses, tissues undergo characteristic microscopic changes that contribute to functional decline, increased vulnerability to chronic disease, and frailty. At the same time, sex-specific hormonal influences shape tissue composition, regenerative capacity, and responses to physiological stress.

This article examines the multifaceted role of English in the modernization of medical education in Uzbekistan. Driven by a globalizing academic landscape and a national imperative to elevate healthcare standards, Uzbek medical institutions have strategically integrated English as a primary medium of instruction. This integration aims to enhance the international competitiveness of graduates, facilitate access to global medical knowledge, and attract international students. The paper explores the strategic drivers, implementation strategies, and challenges encountered, particularly concerning clinical communication and educational quality, discussing the transformative impact on curricula and research. While English proficiency opens avenues for global engagement and academic advancement, persistent challenges necessitate integrated solutions for sustainable modernization.

Maqola mintaqaviy turizmni rivojlantirishda ekskursiya xizmatlarining o‘rni, hududiy turistik resurslarni samarali ishga solish mexanizmlari, servis sifatini oshirish omillari hamda raqamli texnologiyalarni joriy etish imkoniyatlari tahlil qilingan. Mintaqalarda mavjud tabiiy, tarixiy va etnomadaniy meros ob’ektlaridan foydalangan holda barqaror ekskursiya faoliyatini yo‘lga qo‘yish bo‘yicha amaliy takliflar ishlab chiqilgan.

Menstrual sikl ayol organizmidagi murakkab neyroendokrin, gormonal va reproduktiv jarayonlar yig‘indisi bo‘lib, gipotalamus–gipofiz–tuxumdonlar o‘qi orqali boshqariladi. Ushbu tizimning har qanday bo‘g‘inida yuzaga keladigan funksional yoki organik buzilishlar menstrual sikl patofiziologiyasining shakllanishiga olib keladi. Menstrual sikl buzilishlari nafaqat reproduktiv salomatlikka, balki ayol organizmining umumiy metabolik, psixoemotsional va kardiovaskulyar holatiga ham salbiy ta’sir ko‘rsatadi. Gormonal disbalans, yallig‘lanish jarayonlari, metabolik sindrom, stress omillari va genetik moyillik menstrual siklning patofiziologik mexanizmlarini chuqurlashtiruvchi asosiy omillar hisoblanadi.

Ginekologik xirurgiya amaliyotlarining muvaffaqiyati nafaqat operativ texnika va jarroh mahoratiga, balki bemorning biologik muhitiga, xususan, qin mikrobiotasining holatiga ham bevosita bog‘liqdir. Qin mikrobiotasi ayol reproduktiv tizimining muhim himoya mexanizmlaridan biri bo‘lib, uning muvozanatli holati patogen mikroorganizmlarning ko‘payishini cheklaydi va mahalliy immunitetni qo‘llab-quvvatlaydi. Disbioz holatlarida esa laktobatsillarning kamayishi, anaerob va shartli-patogen mikrofloraning ustunlashuvi natijasida to‘qimalarning infeksiyaga sezuvchanligi ortadi. Ushbu maqolada ginekologik xirurgiya amaliyotlari fonida qin mikrobiotasining disbiozi rivojlanish mexanizmlari, uning postopertsion infeksiyalar – endometrit, jarrohlik yarasi infeksiyasi, tos a’zolarining yallig‘lanish kasalliklari kabi asoratlar bilan bog‘liqligi chuqur tahlil qilinadi. Shuningdek, operatsiyadan oldingi va keyingi davrda mikrobiologik skrining, profilaktik antibakterial terapiya va probiotik yondashuvlarning ilmiy asoslari muhokama qilinadi. Tadqiqot natijalari ginekologik xirurgiyada infeksion asoratlarni kamaytirish va bemorlar reabilitatsiyasini yaxshilashga qaratilgan kompleks yondashuvlarning dolzarbligini ko‘rsatadi.
