This article explores the pathophysiological mechanisms underlying the development of hypertension, with a special emphasis on the hormonal factors that contribute to elevated blood pressure. Hypertension, one of the most prevalent cardiovascular disorders worldwide, results from a complex interplay between genetic predisposition, environmental influences, and dysregulation of multiple physiological systems. The article discusses how alterations in renal function, vascular resistance, and sympathetic nervous system activity lead to chronic elevation of arterial pressure. Particular attention is given to the renin-angiotensin-aldosterone system (RAAS), vasopressin, and other endocrine factors such as catecholamines and natriuretic peptides. The review also highlights the feedback loops and receptor sensitivities that sustain hypertensive states over time. Understanding these hormonal contributions is essential for identifying therapeutic targets and improving the management of hypertensive patients. Overall, the paper aims to provide a comprehensive view of how hormonal imbalance acts as a key driver in the pathogenesis of hypertension.
This paper explores the physiological and pathophysiological responses of the human body to stress. Stress, defined as any challenge that disrupts homeostasis, triggers complex mechanisms involving the nervous, endocrine, and immune systems. Acute stress activates adaptive responses, such as the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system, which prepare the body to handle immediate threats. However, chronic stress leads to sustained hormonal imbalances, immune suppression, and increased inflammation, contributing to various diseases including cardiovascular disorders, diabetes, and mental health issues. The dual nature of stress highlights the importance of effective management strategies to maintain health and prevent disease progression. This paper also discusses current understanding of stress-immune system interactions and suggests holistic approaches for stress reduction and health improvement.

Mazkur maqolada sport tadbirlarida marketing strategiyalarining tutgan o‘rni, ularning qo‘llanilish shakllari va samaradorlik darajasi har tomonlama tahlil qilinadi. Sport sohasi zamonaviy jamiyatda nafaqat sog‘lom turmush tarzini targ‘ib qiluvchi ijtimoiy institut, balki katta iqtisodiy salohiyatga ega bo‘lgan tarmoq sifatida ham maydonga chiqmoqda. Xususan, yirik sport tadbirlarining muvaffaqiyatli tashkil etilishi ularning marketing jihatdan to‘g‘ri rejalashtirilganligiga bog‘liq. Maqolada sport marketingining asosiy strategiyalari — brending, raqamli marketing, homiylik aloqalari, auditoriya bilan ishlash va tomoshabinlar tajribasini boshqarish kabi yo‘nalishlar alohida ko‘rib chiqiladi.
Ushbu maqola 15–17 yoshdagi badmintonchilarning tezkorlik va kuch sifatlarini rivojlantirishga qaratilgan ilmiy-tadqiqot natijalarini o‘z ichiga oladi. Tadqiqotda maxsus mashg‘ulotlar tizimi tajriba va nazorat guruhlari o‘rtasida taqqoslash metodikasi asosida sinovdan o‘tkazildi. Tajriba guruhida 8 hafta davomida tezkorlik va mushak kuchi ko‘rsatkichlarini oshirishga yo‘naltirilgan mashg‘ulotlar olib borildi. Natijada sportchilarning harakat faoliyati, reaksiya tezligi va jismoniy holati sezilarli darajada yaxshilandi (p<0,001). Taklif etilgan metodika o‘smir badmintonchilarning tayyorgarligini yangi darajaga ko‘tarishda samaradorligini isbotladi va matematik-statistik tahlil orqali baholandi.
