Varietas toleran salinitas adalah kunci utama pengembangan kacang tanah di tanah salin, namun sampai saat ini belum ada perakitan varietas kacang tanah di Indonesia dengan spesifikasi toleran terhadap salinitas. Penelitian ini bertujuan untuk mengevaluasi toleransi 25 aksesi kacang tanah koleksi plasma nutfah Balai Penelitian Tanaman Aneka Kacang dan Umbi terhadap cekaman salinitas untuk menyediakan sumber gen persilangan tahan salinitas. Aksesi kacang tanah ditanam pada tiga level salinitas yaitu non salin, sedang (5-6 dS/m), dan tinggi (8-10 dS/m). Parameter yang diamati meliputi skor keracunan, kadar K dan Na pada akar dan tajuk, hasil polong dan biji, dan indeks toleransi cekaman (ITC). Hasil penelitian menunjukkan bahwa semua aksesi teridentifikasi peka pada salinitas tinggi. Salinitas sedang merupakan level salinitas tertinggi yang masih dapat ditoleransi oleh 23 aksesi kacang tanah. Pada tingkat salinitas sedang, empat aksesi kacang tanah (MLGA 0211, MLGA 0222, MLGA 0546, MLGA 0570) teridentifikasi toleran, dua aksesi (MLGA 0473 danMLGA 0605) peka, dan 19 aksesi lainnya tergolong sedang. Toleransi terhadap salinitas berhubungan dengan kemampuan aksesi untuk membatasi serapan Na dan translokasinya ke tajuk sehingga rasio K/Na di tajuk tetap tinggi dan dapat meningkatkan proses fotosintesis tanaman. Rasio Na-akar/Na-tajuk sama efektifnya dengan indikator rasio K/Na tajuk, oleh karena itu dapat dijadikan kriteria baru dalam seleksi toleransi kacang tanah terhadap cekaman salinitas. Aksesi yang toleran berdasarkan kemampuan untuk membentuk polong dan biji serta kemampuan menahan efek salinitas dapat dimanfaatkan dan diintegrasikan dalam pemuliaan kacang tanah untuk toleransi salinitas.

Spodoptera litura Fabricius (Lepidoptera: Noctuidae) atau dikenal dengan ulat grayak merupakan hama penting pada tanaman kedelai dan beberapa jenis tanaman penting di Indonesia. Serangan S. litura dapat mengakibatkan kerusakan, bahkan kehilangan hasil pada tanaman kedelai. Gejala serangan berupa daun berlubang karena larva memakan jaringan daun hingga menyisakan epidermis dan tulang daun. Hama ini dilaporkan menyerang tanaman kedelai di sentra-sentra produksi di Indonesia yaitu Aceh, Jawa Barat, Jawa Tengah, Jawa Timur, Nusa Tenggara Barat, Sulawesi Selatan dan dan Sulawesi Tengah. Upaya pengendalian hama ulat grayak yang dilakukan petani adalah menggunakan pestisida sintetik, namun karena dampak negatif penggunaannya terhadap kesehatan manusia dan keseimbangan ekosistem alam, maka perlu adanya alternatif pengendalian yang dampak negatifnya rendah terhadap lingkungan. Beberapa teknologi pengendalian yang telah diteliti dan diketahui efektifitasnya antara lain; penggunaan Spodoptera litura nuclear polyhedrosis virus (SlNPV) (50-100%), cendawan entomopatogen Beauvaria bassiana (51-93%), Metarhizium anisopliae (93-100%), Nomuraea rileyi dan Lecanicillium lecanii (80-85%), Parasitoid (13-56%), predator Forficula auricularia (96%), nematoda entomopatogen Steinernematidae (30-51%), pestisida nabati (&gt;30%), tanaman perangkap dan varietas tahan Aplikasi yang tepat akan mendukung perkembangbiakan spesies tersebut di alam sehingga akan terjadi siklus rantai makanan yang seimbang dan berkelanjutan. Komponen pengendalian ini dapat dimasukkan dalam pengendalian terpadu, sehingga serangan S. litura dapat ditekan, tanaman berproduksi optimal, keseimbangan ekosistem dapat dipertahankan, residu pestisida dapat diturunkan dan sistem pertanian berkelanjutan tercapai.
Chronic venous insufficiency after COVID-19: management of edema and pain syndromes
Authors: Nizamov F. Kh. 
Published: November 2021

Introduction. COVID-19 infection raises many questions regarding the health condition of patients after they have had COVID-19. The aim of this study is to examine the characteristic symptoms of chronic venous insufficiency in the postcovid period.Materials and methods. The materials that were used for work included the results of studying the medical aid appealability, characteristic symptoms, diagnosis and treatment of symptoms of chronic venous insufficiency in persons who have had the coronavirus infection. 47 patients presented with complaints about deterioration of their condition after they had had COVID-19 over March to September 2021 period. Methods: general clinical examiniation, ultrasound angioscanning of veins of the lower extremities, laboratory coagulation tests.Results and discussion. Before deterioration, calf circumference was measured 22–24 cm at a typical measurement site in most patients (89%), after covid infection it reached 26–27 cm. Varicose veins remained soft, without intravascular formations, edema was often bilateral, asymmetric, pain was described as constant (5–6 VAS scores), patients had prominent signs of lymphostasis. 35 out of 47 people received diosmin-based venotonic drug of Russian manufacture at a dose of 1000 mg/day (one tablet twice a day), the course of treatment lasted one to two months. After that period, the edema subsided in 85% of patients, the severity of pain syndrome significantly reduced (up to 2–3 VAS scores). With regard to chronic venous insufficiency in patients with chronic diseases of lower extremity veins (mostly varicose and post-thrombotic diseases), the significant progress of disease was observed in almost 94% of follow-up cases. Diosmin is the main drug that is prescribed to treat chronic venous insufficiency. The drug has an angioprotective and venotonic effect, reduces the vein wall elasticity, increases venous tone, and decreases venous stasis, reduces capillary permeability and fragility, and increases their resistance, improves microcirculation and lymphatic drainage.Сonclusions. In the postcovid period, clinical symptoms of some chronic diseases occur/worsen, including clinical manifestations of chronic venous insufficiency. The use of Russian diosmin-based drug for the management of edema and pain syndrome is very promising.

Published: November 2021

Introduction. Synovial cyst or hygroma is a common disease that occurs in both children and adults, but it is most often observed in people 20–45 years old. More than 60% of patients who go to the polyclinic with complaints about the presence of tumor-like formations have hygroma.Goal. Analysis of the results of treatment of synovial cysts of the hand and wrist joint according to our own observations and literature data.Material and methods. We observed 54 patients suffering from hygroma of the hand and wrist joint, who were treated in polyclinic No. 2 and MEDEL multidisciplinary clinic in Kazan from 2005 to 2020. The treatment of hygrom was carried out using conservative (puncture) and surgical methods. Results. Our experience showed that after a single puncture of the hygroma with the evacuation of its contents (10 patients), relapse developed in all cases. After repeated puncture of the hygroma in 10 patients with evacuation of the contents and subsequent administration of 0.5 ml of betaspan solution, 6 of them did not relapse within 5–6 months, but 4 patients had a relapse in the nearest period (1–2 months). Of the 23 patients who underwent surgery to remove the hygroma, 15 of them had no relapses. In 8 patients in the postoperative period, recurrent hygroma occurred, which could be explained by the ineffectiveness of eliminating the communication zone between the hygroma and the joint.Conclusions. For the successful treatment of this disease, it is important to understand that for the occurrence and development of hygroma, its communication with the joint cavity or tendon vagina is of great importance. In the absence of a message, the successful use of puncture methods of treatment is possible. In the presence of such a message and its detection during preoperative examination, surgical treatment should be planned with mandatory ligation of the leg of the hygroma.

Published: November 2021

O trabalho se propõe a delinear a trajetória do licenciamento enquanto instrumento da política ambiental brasileira, à luz da noção de regulação estatal, extraindo daí elementos analíticos para se compreender a agenda reformista do Congresso Nacional relativa à matéria em discussão na legislatura encerrada em 2018. A partir de uma abordagem analítico-descritiva apoiada em levantamentos bibliográficos e documentais, verificou-se que as mudanças institucionais propostas são informadas por uma percepção do licenciamento ambiental como um processo excessivamente burocratizado que constitui um óbice ao desenvolvimento e se voltam na direção de sua simplificação, tendo em vista conferir maior celeridade à concessão de licenças. Ao final, conclui-se que as novas regras trazem, em seu bojo, o estreitamento das possibilidades de participação da sociedade no processo, bem como de órgãos intervenientes, e a aceleração do trâmite procedimental para a emissão de licenças, afetando o potencial de o instrumento cumprir efetivamente os propósitos delineados na política ambiental de prevenir e mitigar os impactos das atividades socioeconômicas sobre o meio ambiente.
Segment-based resilience response and intervention evaluation of water distribution systems
Authors: Liu Jun , Kang Yinyin 
Published: November 2021

Abstract
The consideration of isolation valves and segments is essential for evaluating the water service and resilience of water distribution systems when shutdowns are required under pipe failure. However, little work has been done on assessing the resilience response and intervention based on segments. This study investigates the impact of intervention (valve density and protection of critical segment) and response (recovery time and recovery sequence) on system resilience taking valve layout into consideration. An algorithm to identify segments based on the graph theory is proposed. Resilience is quantified using the satisfactory rate of the water supply demand. Critical segments are ranked based on resilience analysis. The resilience evaluation method is applied to a case study network. It is found that valve optimization can significantly reduce the number of valves without considerably decreasing the resilience performance. Valve density and the protection of critical segment can reduce the severity of pipe failure, while efficient recovery response can reduce the severity and shorten the duration of pipe failure simultaneously. The criticality of segments depends on the segment location and hydraulic interdependency among segments.

A Hipertensão Arterial Sistêmica (HAS) e o Diabetes Mellitus (DM) fazem parte do rol de Doenças Crônicas Não Transmissíveis (DCNT) mais comuns e com a maior taxa de morbimortalidade, atualmente, no Brasil e no mundo. Diversas complicações estão atreladas a essas patologias dentre elas pode-se destacar a Retinopatia Diabética (RD) e Hipertensiva (RH), sendo a primeira uma causa importante de cegueira adquirida e irreversível no mundo. O presente estudo tem o objetivo de mostrar de forma analítica a importância da realização da Oftalmoscopia pelo médico da Atenção Básica à saúde, à fim de promover um diagnóstico precoce da retinopatia diabética e hipertensiva. Trata-se de uma revisão de literatura, na qual foram incluídos 21 artigos do Scielo, PubMed, Cochrane Libary, Diretrizes brasileiras de HAS e DM, além de dados da OMS e Cadernos e Guias do Ministério da Saúde. A RD e RH estão interligadas ao controle deficitário da glicemia e da pressão arterial. O médico generalista representa uma imagem de suma importância quando se emprega precocemente o exame de fundo de olho nas suas consultas de rotina ambulatorial dentro da Atenção Básica. O Médico da atenção primária da saúde deve estar preparado para aplicação de condutas precoces e exatas, como a realização da oftalmoscopia direta, para viabilizar a redução de danos como a cegueira e gastos públicos. Por fim, é evidente a real necessidade da implementação do aprendizado e realização do exame de fundoscopia pelos profissionais médicos da Unidade Básica de Saúde.

Published: November 2021

Background:
Mild cognitive impairment (MCI) is a state between normal cognition and
dementia. However, MCI diagnosis does not necessarily guarantee the progression to dementia.
Since no previous study investigated brain positron emission tomography (PET) imaging of MCI--
to-normal reversion, we provided PET imaging of MCI- to-normal reversion using the Alzheimer's
Disease Neuroimaging Initiative (ADNI) database.

Methods:
We applied comprehensive neuropsychological criteria (NP criteria), consisting of memory,
language, and attention/executive function domains, to include patients with a baseline diagnosis
of MCI (n=613). According to the criteria, the year 1 status of the patients was categorized into
three groups (reversion: n=105, stable MCI: n=422, conversion: n=86). Demographic, neuropsychological,
genetic, CSF, and cognition biomarker variables were compared between the groups. Additionally,
after adjustment for confounding variables, the deposition pattern of amyloid-β and cerebral
glucose metabolism were compared between three groups via AV45- and FDG-PET modalities,
respectively.

Results:
MCI reversion rate was 17.1% during one year of follow-up. The reversion group had the
lowest frequency of APOE ε4+ subjects, the highest CSF level of amyloid-β, and the lowest CSF
levels of t-tau and p-tau. Neuropsychological assessments were also suggestive of better cognitive
performance in the reversion group. Patients with reversion to normal state had higher glucose
metabolism in bilateral angular and left middle/inferior temporal gyri, when compared to those
with stable MCI state. Meanwhile, lower amyloid-β deposition at baseline was observed in the frontal
and parietal regions of the reverted subjects. On the other hand, the conversion group showed
lower cerebral glucose metabolism in bilateral angular and bilateral middle/inferior temporal gyri
compared to the stable MCI group, whereas the amyloid-β accumulation was similar between the
groups.

Conclusions:
This longitudinal study provides novel insight regarding the application of PET imaging
in predicting MCI transition over time.
