В настоящее время известно более 3000 уникальных цинковых белков, играющих важную роль в многочисленных физиологических процессах, включая репарацию и регенерацию кожи. Процесс ранозаживления включает несколько фаз: гемостаз, воспаление, пролиферацию клеток, реэпителизацию, грануляцию и ангиогенез, ремоделирование матрикса и образование рубцов. Физиологическая роль цинка во всех этих фазах не вызывает сомнений. В многокомпонентном каскадном механизме ранозаживления важно противовоспалительное, мембраностабилизирующее и эпителизирующее действие цинка. В настоящее время изучена роль этого микроэлемента в тромбоцитарном и сосудистом гемостазе и показано, что наряду с ионами кальция цинк повышает активность и агрегацию тромбоцитов и участвует в формировании фибринового сгустка. Многочисленные исследования демонстрируют участие цинка в работе иммунной системы, а также его влияние на продукцию цитокинов путем снижения активации ядерного фактора kappa B (NF-kB), однако механизмы регуляции NF-kВ пути до конца не ясны. Таким образом, несмотря на то что дерматотропное действие цинка очевидно, его роль в процессе восстановления кожных покровов до конца не изучена и имеет много «белых пятен». В настоящем обзоре представлен анализ научных работ, в которых изучается участие цинка в молекулярных механизмах ранозаживления. Показано, что роль цинка опосредована цинксодержащими белками, понимание роли которых остается одной из приоритетных задач, актуальной для терапии раневых повреждений кожи.

Синтетический аморфный кремнезем (SiO2) широко используется в пищевой, фармацевтической и косметической промышленности. Он является одним из обязательных составных компонентов разрыхлителей, антислеживателей, загустителей, а также применяется для очистки различных спиртосодержащих жидкостей, включая пиво и вина. Считается, что SiO2 инертен и биологически неактивен, и поэтому безопасен для здоровья человека в применяемых концентрациях и дозах. Тем не менее промышленные образцы SiO2 содержат значительную долю наночастиц соединений кремния, и многочисленные исследования доказали, что наночастицы, в силу размеров, обладают особыми биологическими свойствами. Сведения о долгосрочных биологических эффектах наночастиц SiO2, выходящих за сроки проведения классических токсикологических экспериментов, не систематизированы. Цель обзора – систематизация сведений о возможном влиянии соединений кремния, поступающих в организм человека с питьевой водой, продуктами питания и вдыхаемым воздухом, на ключевые патогенетические механизмы развития атеросклероза. В обзоре систематизированы находящиеся в свободном доступе работы, посвящённые изучению влияния неорганических соединений кремния, в первую очередь SiO2, на известные механизмы атерогенеза. Частицы нанокристаллического SiO2 (размером от 30 до 58 нм), используемые в промышленности как in vivo, так и in vitro, дозозависимо стимулируют образование активных форм кислорода и оксида азота, активируют клеточный и коагуляционный гемостаз. Таким образом, наночастицы играют определенную роль в развитии повреждений эндотелия. Нанокристаллический SiO2 также повышает активность макрофагов и активирует воспалительный каскад. Токсичное действие наночастиц SiO2 обратно пропорционально их размеру, и чем меньше размер наночастиц, тем больше токсический эффект. Установлено, что наночастицы кремния усиливают своё негативное влияние в присутствии наночастиц диоксида титана и при сочетании с воздействием холода. Сделано заключение, что SiO2, широко используемый в пищевой, фармацевтической и косметической промышленностях, непосредственно влияет на все ключевые этапы формирования атероматозной бляшки, и соответственно, нельзя исключить избыточное поступление SiO2 в организм из факторов риска развития сердечно-сосудистых заболеваний.

Изучение влияния токсичных металлов на развитие патологических процессов  важное и необходимое направление исследований. Сурьма и олово, являясь токсичными металлами, могут оказывать нежелательные эффекты на организм человека и вызывать развитие заболеваний. Целью данного исследования являлось изучение возможного влияния олова и сурьмы на развитие воспалительных реакций. Были оценены корреляции между концентрациями этих элементов и показателями С-реактивного белка (как основного маркёра воспаления) в сыворотке крови. Также были рассчитаны референсные значения концентраций олова и сурьмы в сыворотке крови по методу Хоффмана. Исследование проведено на основании базы данных лабораторных анализов людей в возрасте от 18 до 80 лет. Были проанализированы уровни олова и сурьмы методом МС-ИСП, а также уровень С-реактивного белка иммунотурбидиметрическим методом в сыворотке крови. В ходе исследования было выявлено, что сурьма имеет слабые, но статистически значимые корреляции с С-реактивным белком (r < 0,200, p < 0,01) и в общей выборке, и среди мужчин и женщин по отдельности. При разделении по возрасту в группе обследованных от 18 до 25 лет корреляции с С-реактивным белком наблюдались как у сурьмы, так и у олова. При этом сурьма демонстрировала отрицательные корреляции (p < 0,05), а олово - положительные (p < 0,05). Полученные результаты свидетельствуют о том, что концентрации олова и сурьмы в сыворотке крови не являются специфичными маркёрами воспалительного процесса, однако их следует учитывать при обследовании лиц, контактирующих с указанными металлами, для предупреждения развития патологических процессов.

Из цикла валерианы лекарственной (Valeriana officinalis L. s. I.) в Воронежской области произрастают валериана волжская (Valeriana wolgensis Kazak.) и валериана сомнительная (Valeriana dubia Bunge), которые характеризуются сходными морфологическими признаками. Не только на территории РФ и стан бывшего СССР, но и в Европе очень популярны лекарственные растительные препараты с корнем валерианы для снятия легких симптомов психического стресса и для улучшения сна. В последние годы, актуальным направлением фармакогнозии является комплексное изучение лекарственных растений различных видов, позволяющие обосновать целесообразность заготовки и других органов и частей, неописанных в нормативной документации, с целью рационального природопользования ограниченными растительными ресурсами. Так, перспективным является фармакогностическое изучение надземных органов валерианы исследуемых видов, как потенциального источника биологически активных веществ. Методом масс-спектрометрии проведено исследование элементного состава корневищ с корнями, травы валерианы волжской и валерианы сомнительной, а также почв с мест произрастания. Определено содержание 6 макро- (Al, Ca, K, Mg, Na, P) и 59 микро- и ультрамикроэлементов. Данные свидетельствуют о том, что свинец, мышьяк и кадмий накапливаются в корневищах с корнями более интенсивно по сравнению с травой: в 5–7 раз, в 1,5 раза и в 3,5–4,5 раза соответственно. Ртуть более активно накапливается надземными органами – в 1,5–2,0 раза по сравнению с подземными. Суммарное содержание токсичных элементов в корневищах с корнями валерианы волжской примерно в 6,5 раза выше, чем у аналогичного вида сырья валерианы сомнительной. Содержание токсичных нормированных элементов в почве в 7–9 раз выше, чем в исследованных подземных органах, и почти в 70–90 раз. Ценность лекарственного растительного сырья напрямую зависит от его экологической безопасности. Анализ содержания токсичных элементов в исследуемых образцах показал, что их количество не превышает допустимых норм. Определены значения коэффициентов биологического поглощения элементов для сырья валериан исследуемых видов. По способности накапливать нормируемые токсичные элементы траву изучаемых видов валериан можно отнести к безопасному растительному сырью вне зависимости от района заготовки. Корневища с корнями валерианы сомнительной имеют тенденцию к активному поглощению кадмия из почвы, что свидетельствует о нецелесообразности сбора подземных органов вдоль оживленных автомагистралей и предприятий металлургии.

Published: April 2022

Soft-tissue management and subsequent salvage of the lower extremity following trauma has long presented difficult challenges to the plastic surgeon. Trauma to the lower extremity can produce long-term sequelae consisting of psychological trauma, functional deficits, and increased costs to the healthcare system. Avoiding incorrect management is important, and is compounded by the fact that few guidelines exist on appropriate treatment and patient counseling. This study aims to describe the authors’ experience at a large limb salvage center in order to further delineate management strategies.

Authors: Kung Janet Wui Cheung , Ng Kelvin Kwok Chai
Published: April 2022

Hepatocellular carcinoma (HCC) was the sixth most common cancer and the third cause of cancer-related deaths worldwide in 2020. Liver resection and transplantation remain the cornerstone for patients with early-stage disease and represent the only option for potential cure in HCC. However, fewer than 10% of patients are considered suitable for surgery at the time of diagnosis. Locoregional therapies, defined as minimally invasive image-guided liver tumour-directed procedures, are integral to in the management of HCC. This review discusses the role of locoregional therapies in HCC management in the emergence of immune and systemic treatments.
Chapter: imaging of atrial and ventricular septal defects
Authors: Uppu Santosh C.
Published: April 2022

Septal defects together account for the majority of the congenital heart defects (CHD); these can occur in isolation or associated with other CHDs. Hemodynamic manifestations are dependent upon the size, location, and the number of the defects, along with the associated lesions. For example, atrial septal defects result in the right ventricular volume overload, whereas the ventricular septal defect (VSD) results in the left heart volume overload. Knowledge of septal anatomy is crucial to understanding these lesions, their hemodynamic significance, and thus better plan management, including interventions. Noninvasive imaging of simple septal defects by various modalities will be reviewed; atrioventricular septal defects, anomalous pulmonary venous connections, patent ductus arteriosus, and complex cardiac conditions with VSD will not be discussed in this chapter.

Published: April 2022

Late-life depression (LLD) is a common complex mood disorder with high comorbidity of both psychiatric and physical diseases, cognitive decline, and increased mortality. The mechanisms underlying LLD are incompletely understood. The heterogeneity of depression complicates research into the underlying mechanisms, and factors involved in LLD may differ from those involved in early-life depression. This narrative review provides an overview of (micro-)vascular and metabolic factors involved in the development of LLD. Evidence suggests that cerebral small vessel disease, generalized microvascular dysfunction, and metabolic risk factors, including diabetes and inflammation, may contribute to the development of LLD, while the role of neurodegeneration needs further in-depth investigation. Accordingly, vascular and metabolic factors may provide promising targets for the prevention and improvement of treatment of LLD. Guidelines to screen for LLD in cardiovascular care need further implementation, as do integrated care approaches that treat LLD and diabetes jointly. However, intervention studies are needed to assess which interventions are appropriate and most effective in clinical practice.
Diagnosis of cardiac murmurs in children
Authors: Rao P. Syamasundar
Published: April 2022

Heart murmurs are frequently heard, and the murmurs are the usual cause for uncovering heart defects in pediatric patients. The murmurs are grouped into systolic murmurs, diastolic murmurs, and continuous murmurs. Cautious assessment of the murmur and associated abnormalities in physical examination are likely to produce correct diagnosis of the cause of the murmur. Sometimes it may be necessary to utilize noninvasive and invasive (rarely) investigations to achieve an accurate diagnosis. Nonetheless, such diagnostic studies may frequently be required for quantification, and before intervention either by transcatheter methods or by surgery.

Published: April 2022

Rare diseases are complex and difficult to diagnose, with parents and caregivers often reporting significant delays in receiving a definitive diagnosis. Following diagnosis, parents and caregivers often feel overwhelmed with emotions, including relief, guilt, and shock. The culmination of this emotional burden may lead to a deterioration of psychological health, ultimately reaching a stage where the parents struggle to cope. A systematic literature review was conducted of the articles on this topic by searching the electronic database, PubMed. Further studies were retrieved from a reference listing of relevant articles and consultation with experts in the field. The review was based on the guidance in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. The initial search identified 1276 articles, of which 37 met the inclusion criteria and were included in this review. The literature revealed key factors that appeared to contribute to psychological stress, including prolonged diagnostic odyssey, poor diagnostic delivery, lack of information and specialist knowledge, and convoluted healthcare systems. This review reinforces the need for psychological support amongst parents and caregivers of children with a rare disease at the time of diagnosis. The results of this literature review will be used to develop a statement of good practice for the support of parents and caregivers when a rare disease diagnosis is given.

Infiltration is part of the hydrologic cycle, namely the process of entering water from the surface into the soil. Infiltration is affected by vegetation, slope dan soil type. This study aims to analyze the amount of capacity and volume of infiltration in open land, shrubs and rubber plantations in the DAS Dua Laut. The reseach method uses the Horton formula with the observation point using purposive sampling with regard to various land cover and slope classes. The results showed that the highest value of infiltration capacity in rubber plantation land cover at slopes of 0-8% with a value of 1.182 mm/jam and the lowest in open land at slopes of 15-25% with a value of 0.402 mm/jam. The highest infiltration volume value in rubber plantations is 0.734 mm³ while the lowest value in open land is 0.131 mm³. this shows that the higher the slope, the smaller the infiltration and the land that has vegetation the infiltration tends to be greater. The level of slope of the land in the DAS Dua Laut affects the rate of infiltration. Infiltration rate can be categorized as slow and very slow. This is influenced by the type of soil which is clay and dusty clay.Keywords; infiltration; capacity and volume of infiltration; DAS Dua Laut
