Ushbu ishning dolzarbligi doimiy donorlar qonida past zichlikdagi lipoproteidlarni aniqlash va o'rganish qon aylanish tizimi va tarkibi bilan bog'liq moddalar almashinuvining buzilish yog'lar almashinuvi va xolesterin miqdorining o’zgarishi bilan bog'liq kasalliklar jumladan yurak-qon tomir tizimidagi kasalliklar: ateroskleroz, yurak ishemik kasalliklari, arterial gipertenziya, mikrosirkulyator tizim kasalliklari, periferik a’zolarda tromboz, emboliya, ishemiya kabi o'g'ir asoratlarga olib keluvchi o'zgarishlarning donor bo'lmagan insonlarga nisbatan kam uchrashini ilmiy-amaliy jihatdan yoritib berishdir. Ateroskleroz va uning asoratlari jiddiy tibbiy-ijtimoiy muammo bo'lib, bemorlar soni bo'yicha u boshqa yurak qon tomir tizimi kasalliklarga nisbatan dunyoda birinchi o'rinlardan birini egallaydi. PZL (past zichlikdagi lipoproteidlar) bilan bog'liq patologiyalar birinchi marta klinik jihatdan eng mehnatga layoqatli yoshda (30-50 yosh) namoyon bo'ladi va asorat berish tendentsiyasiga ega. So'nggi yillarda yoshlik davrida ateroskleroz va uning asoratlari bilan bog’liq yurak qon tomir kasalliklari o'sishiga nisbatan barqaror tendentsiya kuzatilmoqda.

In recent decades, the prevalence of allergic respiratory diseases, such as asthma and allergic rhinitis, in children has been rising at an alarming rate. One of the key contributors to this trend is climate change, which has altered environmental conditions, exacerbating the frequency and intensity of allergens such as pollen, mold, and air pollutants. This paper examines the dynamics of the increasing incidence of allergic respiratory diseases in children under the conditions of climate change. It explores the key environmental factors-such as rising temperatures, longer pollen seasons, and worsening air quality-that contribute to this growing health concern. The paper also delves into the vulnerability of children, whose developing immune and respiratory systems make them more susceptible to environmental stressors. In addition, it emphasizes the importance of preventive measures, including environmental regulation, early detection, allergen avoidance strategies, and public health policies aimed at reducing exposure to harmful environmental factors.

Major financial crises often have widespread impacts beyond the economic fallout. This article examines the influence of crises like the Global Financial Crisis (GFC) of 2008 on consumer behaviour and market dynamics. It analyzes changes in spending patterns, preferences, and brand loyalty using quantitative data from surveys as well as financial and firm reports. Key theories linking wealth effects and uncertainty with consumption are also explored. Research into this topic has been done to have a more clear view about the buying behavior and market condition. There also have been made conclusions how to deal with the market and consumers if the identical crisis happens.
