АНТРОПОЛОГИЧЕСКАЯ ХАРАКТЕРИСТИКА ЭКСТРАОРДИНАРНОГО ЧЕРЕПА ИЗ с. ТХИНА (АБХАЗИЯ)*
Authors: Веселовская Елизавета Валентиновна , Григорьева Ольга Михайловна , Бурцев Игорь Дмитриевич 
Published: December 2020

Настоящая работа посвящена изучению необычного черепа из раскопок кладбища у с. Тхина Очамчирского района, Абхазия. Череп с нижней челюстью, очень крупных размеров с ярко выраженным рельефом. Исследовали краниологические особенности черепа и черты внешнего облика индивида по выполненным на его основе графической и скульптурной реконструкциям. Принадлежность данного индивида к виду современного человека Homo sapiens не вызывает сомнений; возможно, присутствуют черты экваториального антропологического типа. Выраженное своеобразие, связанное с укрупнением общих размеров черепа и значительным развитием рельефа, может быть результатом гетерозиса при метисации далеко отстоящих антропологических типов, к которым принадлежали его родители.
This work is devoted to the study of a very unusual skull from the village of Thina, Abkhazia. The skull has the lower jaw, is very large and rather robust with pronounced relief. The metric traits of this skull and its external appearance were studied based on graphic and sculptural reconstructions made from it. It is concluded that this individual belongs to the modern human species Homo sapiens, one of its Equatorial variants. The unusual appearance of the skull might be explained by heterosis caused by possible miscegenation in this individual’s ancestors.

Authors: Квилинкова Елизавета Николаевна 
Published: December 2020

Статья посвящена Михаилу Николаевичу Губогло – известному ученому, профессору, который является одним из основателей российской этносоциологии и гагаузской этнологии. В статье анализируется практическая значимость использованных им новых этносоциологических методов и подходов в контексте гагаузской проблематики. Отмечается, что он исследовал не только вопросы этногенеза гагаузов, но и культуру повседневности этого народа. Рассматривается использованный им в работах подход, с помощью которого он в системе этнологического знания исследовал идентичности гагаузов, социальные функции их повседневности в послевоенный период и др. Констатируется, что примененный им биографический и автобиографический метод позволил проследить судьбу различных элементов соционормативной культуры гагаузов.
Раскрываются основные области вклада М.Н. Губогло в молдавскую этнологию и гагаузоведение. По его идее и под его руководством был успешно реализован ряд крупных масштабных проектов: проведены российско-молдавские симпозиумы, опубликованы коллективные монографии в престижной серии «Народы и культуры», изданы сборники и др. Благодаря приложенным им усилиям был дан мощный импульс молдавской этнологии, активизировались междисциплинарные исследования. Подчеркивается, что он внес неоценимый вклад в развитие молдавского гагаузоведения. Делается вывод о том, что в первом десятилетии XXI века состоялся переход гагаузоведения от описательной этнографии к аналитической этнологии.
The article is dedicated to Mikhail Nikolaevich Guboglo – a famous scientist, professor, who is one of the founders of Russian ethno-sociology and Gagauz ethnology. The article analyzes the practical values of his new ethno-sociological methods and approaches in the context of Gagauz studies. It is noted that he studied not only the ethnogenesis of the Gagauz people, but also their everyday culture and lifestyles. The article examines the approach he developed to investigate the identities of the Gagauzes, the social functions of their everyday life in the post-war and other periods in the system of ethnological knowledge. The author argues that the biographical and autobiographical method he used allowed him to trace the fate of various elements of the socio-normative culture of the Gagauz people.
The main areas of M.N. Guboglo’s contribution to Moldavian ethnology and Gagauz studies are revealed. According to his idea and under his leadership, a number of large-scale projects were successfully implemented: Russian-Moldavian symposia were held, collective monographs were published in the prestigious series “Peoples and Cultures”, collections were printed etc. Thanks to his efforts, a powerful impetus was given to Moldovan ethnology, and interdisciplinary research intensified. It is emphasized that he made an invaluable contribution to the development of Moldavian Gagauz studies. It is concluded that in the first decade of the 21st century, Gagauz studies transformed from descriptive ethnography to analytical ethnology.

Cisplatin is extensively used and is highly effective in clinical oncology; nevertheless, nephrotoxicity has severely limited its widespread utility. Isoquercitrin (IQC), a natural flavonoid widely found in herbage, is well known and recognized for its antioxidant, anti-inflammatory, and anti-apoptotic properties. However, the potential effects and mechanism of IQC in cisplatin-induced acute kidney diseases remain unknown. In this study, we postulated the potential effects and mechanism of IQC upon cisplatin exposurein vivoandin vitro. For thein vivostudy, C57BL/6J mice were pretreated with IQC or saline (50 mg/kg/day) by gavage for 3 days before cisplatin single injection (25 mg/kg). Renal function, apoptosis, inflammation, oxidative stress and p-ERK were measured to evaluate kidney injury.In vitro, mouse proximal tubular cells (mPTCs) and human proximal tubule epithelial cell line (HK2) were pretreated with or without IQC (80 μM for mPTCs and 120 μM for HK2) for 2 h and then co-administrated with cisplatin for another 24 h. Apoptosis, inflammation, ROS and p-ERK of cells were also measured.In vivo, IQC administration strikingly reduced cisplatin-induced nephrotoxicity as evidenced by the improvement in renal function (serum creatinine and blood urea nitrogen), kidney histology (PAS staining), apoptotic molecules (cleaved caspase-3, caspase-8, Bax and Bcl-2), inﬂammatory cytokines (IL-1β, IL-6, TNF-α, and COX-2), oxidative stress (MDA and total glutathione) and p-ERK. In line within vivofindings, IQC markedly protected against cisplatin-induced cell injury in mPTCs and HK2 cells. Collectively, these findings demonstrated that IQC administration could significantly protect against cisplatin nephrotoxicity possibly through ameliorating apoptosis, inflammation and oxidative stress accompanied by cross talk with p-ERK. Furthermore, IQC may have potential therapeutic uses in the treatment of cisplatin-induced acute kidney injury.

BackgroundMiscarriage is a common complication of early pregnancy, mostly occurring in the first trimester. However, the etiological factors and prognostic and diagnostic biomarkers are not well known. Neurokinin-1 receptor (NK-1R) is a receptor of tachykinin peptide substance P (SP) and has a role in various pathological conditions, cancers, but its association with miscarriages and significance as a clinicopathological parameter are not studied. Accordingly, the present study aimed to clarify the localization and expression for NK-1R in human retained products of conception (POC). The role of NK-1R is not known in miscarriages.Materials and MethodsNK-1R expression was assessed in POC and normal placental tissues by immunohistochemistry. Three- to four-micrometer-thin sections of formalin-fixed paraffin-embedded tissues were used for this purpose. Tissues were processed and then immunohistochemically stained with NK-1R antibody. Brain tissue was used as control for antibody. Protein expression was evaluated using the nuclear labeling index (%). Tissues were counterstained with 3,3′-diaminobenzidine (DAB), and microscopy was performed at 10×, 20×, and 40× magnifications.ResultsTen human POC tissues and 10 normal placental tissues were studied by immunohistochemistry to demonstrate the localization of NK-1R. The expression of NK-1R protein was high in all the cases of both groups. NK-1R expression showed no notable differences among different cases of miscarriages as well as normal deliveries at full term regardless of the mother’s age and gestational age at which the event occurred. Statistically, no difference was found in both groups, which is in agreement with our hypothesis and previous findings.ConclusionThe expression of NK-1R was similar in all the cases, and it was intense. It shows that dysregulation of NK-1R along with its ligand SP might be involved in miscarriages and also involved in normal delivery. Our results provide fundamental data regarding this anti-NK-1R strategy. Thus, the present study recommends that SP/NK-1R system might, therefore, be considered as an emerging and promising diagnostic and therapeutic strategy against miscarriages. Hence, we report for the first time the expression and localization of NK-1R in POC. We suggest NK-1R antagonist in addition to the immunoglobulins and human chorionic gonadotropin to diagnose and treat spontaneous miscarriages.

Published: December 2020

PurposeTo examine physiological and technical responses to repeated-sprint training in normobaric hypoxia at ∼3,000 m (RSH, n = 11) or in normoxia (RSN, n = 11) compared to a control group (CON, n = 8) in well-trained tennis players. Participants were 28.8 ± 5.9 years old without any previous experience of training in hypoxia.MethodsIn addition to maintaining their usual training (CON), both RSH and RSN groups completed five tennis specific repeated-shuttle sprint sessions (4 × 5 × ∼8 s maximal sprints with ∼22 s passive recovery and ∼5 min rest between sets) over 12 days. Before (Pre), the week after (Post-1) and 3 weeks after Post-1 (Post-2), physical/technical performance during Test to Exhaustion Specific to Tennis (TEST), repeated-sprint ability (RSA) (8 × ∼20 m shuttle runs—departing every 20 s) and heart rate variability (HRV) were assessed.ResultsFrom Pre to Post-1 and Post-2, RSH improved TEST time to exhaustion (+18.2 and +17.3%; both P &lt; 0.001), while the “onset of blood lactate accumulation” at 4 mmol L–1 occurred at later stages (+24.4 and +19.8%, both P &lt; 0.01). At the same time points, ball accuracy at 100% V̇O2max increased in RSH only (+38.2%, P = 0.003 and +40.9%, P = 0.007). Markers of TEST performance did not change for both RSN and CON. Compared to Pre, RSA total time increased significantly at Post-1 and Post-2 (−1.9 and −2.5%, P &lt; 0.05) in RSH only and this was accompanied by larger absolute Δ total hemoglobin (+82.5 and +137%, both P &lt; 0.001). HRV did not change either supine or standing positions.ConclusionFive repeated sprint training sessions in hypoxia using tennis specific shuttle runs improve physiological and technical responses to TEST, RSA, and accompanying muscle perfusion responses in well-trained tennis players.

Published: December 2020

As escalas de sintomas de deficiência visual desempenham um importante papel, auxiliando o produtor agrícola a identificar, no campo, as possíveis deficiências de macro e micronutrientes. Sabendo-se disso, o objetivo desse trabalho foi avaliar a omissão de macro e micronutrientes no desenvolvimento da cultura da alface (Jonction – cultivar do tipo crespa), identificando e descrevendo os sintomas visuais e morfológicos causados pela omissão de nutrientes. O delineamento experimental foi inteiramente casualizado com 11 tratamentos e 3 repetições, totalizando 33 unidades experimentais. Os tratamentos consistiram na fertirrigação das unidades experimentais com a solução completa e da solução completa com omissão de nitrogênio (N), fósforo (P), potássio (K), cálcio (Ca), magnésio (Mg), enxofre (S), ferro (Fe), manganês (Mn), zinco (Zn) e boro (B). A escala visual dos sintomas de deficiência foi realizada por meio de fotos semanais (seis semanas). Também foram avaliados: peso verde da parte aérea (PVPA) e parte radicular (PVPR); peso seco da parte aérea (PSPA) e parte radicular (PSPR) e comprimento de raiz (CR) na cultura da alface, ao final do experimento. O efeito supressor na cultura da alface durante a omissão dos macronutrientes na solução nutritiva foi na seguinte ordem: P, K, Ca e Mg; e para micronutrientes foi na seguinte ordem: Mn, B, Zn e Fe. A ausência de P na solução nutritiva foi a principal limitante para o desenvolvimento da cultura da alface.
ORDER FIKTIF TERHADAP DRIVER GOJEK DAN UPAYA PERLINDUNGANNYA
Authors: Renandani Inka , Suliantoro Adi 
Published: December 2020

Pengangkutan merupakan aspek yang sangat penting keberadaanya dalam masyarakat, baik pengangkutan orang maupun barang. Salah satu perusahaan transportasi online yang terkenal di Indonesia adalah PT.Gojek Indonesia. Pada perkembagannya, muncul perbuatan yang dilakukan oleh oknum masyarakat yang merugikan para driver ojek online, yaitu order fiktif / palsu. Order Fiktif adalah membuat pesanan yang diawali membuat akun palsu melalui aplikasi transportasi online yang dapat merugikan perusahaan.
Permasalahannya adalah bagaimanakah bentuk perjanjian antara driver dengan pengguna dan adakah tanggung jawab dari PT Gojek Indonesia. Metode yang digunakan dalam penelitian ini adalah Yuridis Sosiologis, dengan sumber data berupa wawancara. Hasil Analisa dipaparkan secara deskriptif analitis.
Hasil penelitian menunjukan bahwa belum ada peraturan hukum yang mengatur tentang perlindungan bagi driver Gojek yang mengalami order fiktif. Tetapi dari pihak PT. Gojek memberikan kompensasi berupa uang ganti rugi. Namun hal ini tidak banyak digunakan oleh para driver , karena proses pencairan uang ganti rugi yang membutuhkan waktu, sehingga driver selaku korban lebih memilih membawa sendiri hasil dari pesanan fiktif tersebut atau menjualnya lagi kepada orang lain.
