Published: July 2024

Background: Climate change is an environmental issue that affects a lot of human activities and causes damages to the Earth which of course will have linkages to the living creatures’ life. Agriculture is a part of human activities that becomes a source of human life and influences food security. It also contributes to generating oxygen (O2) and absorbing carbon dioxide (CO2) in the air. As climate change is getting uncertain each time and influenced by some factors that make climate change getting worse, this gives some impacts on agriculture and food security. Besides, there will be other issues that come from agriculture and food security matters due to climate change, such as hunger due to food crisis, etc. Thereupon, we need to know the effects of climate change on agriculture and food security to mitigate and adapt to climate change. The objective of this literature study is to elucidate the impacts of climate change on agriculture and food security to understand the things that should be done to tackle the possibilities of bad impacts on human life. Methods: The method that was implemented was a qualitative method that utilized literature review to do the identification, evaluation and collecting information that was needed. Some papers and journals related to climate change, agriculture, and food security were used in literature review. Findings: Food production from crops and livestock is crucial for global food security. However, significant challenges to food production arise due to climate change and related factors. Heat exposure significantly affects livestock performance and welfare. Climate change also leads to soil erosion, resulting in decreased soil productivity, loss of carbon and organic nutrients, and reduced soil fertility. Conclusion: It is suggested to comprehend the effects of climate change on agriculture that will influence food security along with the well-being of people in running life.

Published: July 2024

В мае на станции Челябинск-Главный проведены предварительные испытания разработки АО «НИИАС» – комбинированной схемы закрепления подвижного состава. Уникальная технология совмещения устройств закрепления, взаимодействующих с колесом подвижного состава на различных принципах, позволяет сократить капитальные затраты на внедрение решения более чем в 2 раза. Преимуществом технологии является возможность ее использования на путях с большими уклонами до 2,5 ‰. При этом количество устройств, а, следовательно, и стоимость решения, не растет с увеличением уклона. Разработка является частью проекта «Цифровая железнодорожная станция». Первой станцией, где будет применяться комбинированная схема, станет Челябинск-Главный. По итогам проведенных испытаний принято решение о работоспособности технологии и необходимости проведения эксплуатационных испытаний. Массовое внедрение разработки на сети планируется начать с 2025 г.
In May, preliminary tests of the development of JSC NIIAS, a combined scheme for securing rolling stock, were conducted at the Chelyabinsk-Glavny station. The unique technology of combining fastening devices interacting with the rolling stock wheel on various principles allows you to reduce the capital costs of implementing the solution by more than 2 times. The advantage of the technology is the possibility of its use on tracks with high slopes up to 2,5 ‰. At the same time, the number of devices, and, consequently, the cost of the solution, does not increase with increasing bias. The development is part of the Digital Railway Station project. The first station to use the combined scheme will be Chelyabinsk-the Main One. Based on the results of the tests, a decision was made on the operability of the technology and the need for operational tests.

Published: July 2024

Background
Gingivitis is an inflammation of the gums that is the initial cause of the development of periodontal disease by the activity of Nuclear Factor-kappa B (NF-κB), Interleukin-1β (IL-1β), Interleukin-6 (IL-6), p38, and Tumor Necrosis Factor-α (TNF-α). Unaddressed chronic inflammation can lead to persistent disturbances in other parts of the body. Brazilin is a naturally occurring plant chemical that may have antibacterial and anti-inflammatory effects. Treatment based on the natural plant compound, brazilin, is developed in the form of a topical cream for easy application.

Objective
The aim is to develop the natural compound brazilin in the form of a topical cream as an anti-inflammatory agent to reduce NF-κB expression through Imunohistochemistry (IHC) methods, and the expression of pro-inflammatory genes IL-1β, IL-6, p38, and TNF-α.

Methods
Male Sprague-Dawley rats were induced with gingivitis using P. gingivalis bacteria. The observed groups included rats treated with a single application of brazilin cream and rats treated with two applications of brazilin cream. The treatment was administered for 15 days. On days 3, 6, 9, 12, and 15, anatomical wound observations and wound histology using hematoxylin-eosin and Masson’s Trichrome staining were performed. NF-κB protein expression was analyzed using the IHC method. Gingival inflammation gene expression of NF-κB, IL-1β, IL-6, p38, and TNF-α was measured using q-RTPCR.

Results
Single and double applications of brazilin cream increased angiogenesis and decreased NF-κB protein expression, in addition to the IL-1β, IL-6, p38, and TNF-α gene expressions.

Conclusion
In a rat gingivitis model, Brazilin cream may function as an anti-inflammatory agent in the gingival tissue.

Published: July 2024

Background
This study aimed to compare the perceived masticatory ability (PrMA) in completely edentulous patients (EDPs) with thermoplastic conventional complete dentures (CDs) versus single implant-retained mandibular overdentures.

Methods
The current study was conducted in the outpatient Prosthodontic Clinic, Faculty of Dental Medicine, Al-Azhar University, Cairo, Egypt. PrMA was evaluated in 45 completely edentulous patients (46% males, mean age 50.4 ± 4.7 years). Each patient received a thermoplastic PMMA complete denture (Polyan IC TM Bredent GmbH & Co.KG, Germany). The PrMA was evaluated at one-month and six-month intervals of denture use. An immediate loading single implant was placed into the mid-symphyseal for each patient, and the denture was adjusted. Subsequently, the PrMA was reevaluated after one month and six months. The data were collected and statistically analyzed using the SPSS@V25 to assess the changes in PrMA.

Results
The PrMA demonstrated improvement after six months of thermoplastic conventional denture use. However, this improvement was not statistically significant (p = 0.405). In addition, the PrMA showed a substantial increase following a single implant placement at one and six months (p < 0.001) of the overdenture use compared to the conventional denture. The PrMA insignificantly improved (p = 0.397) after six months of the single implant retained overdenture use.

Discussion
The study’s findings indicate that using immediate loading single implant-retained mandibular overdentures significantly improved PrMA in completely edentulous patients.

Published: July 2024

Out of the 1.5 billion ha (11% of the world’s land surface of 13.4 billion ha) of cropland worldwide, 1.20 (80%) billion ha is rainfed, and 60 percent of the world’s food comes from rainfed areas. In India, rainfed agriculture occupies about 51 percent of the country’s net sown area and accounts for nearly 40 percent of the total food production. In HP, over 10% area of the state is under cultivation, of which about 81% is rainfed, facing frequent water scarcity. Watershed development constitutes a holistic strategy aimed at enhancing the resilience and productivity of rainfed farming systems. This approach integrates various interventions targeting soil and water conservation, afforestation, agricultural practices, and socio-economic empowerment of local communities. The essence of watershed development lies in its comprehensive and participatory nature, which addresses the complex interactions among hydrological, ecological, and socio-economic factors influencing rainfed agriculture. Through the implementation of watershed management techniques, such as contour bunding, check dams and afforestation, soil erosion is minimized, water resources are conserved, and micro-climatic conditions are ameliorated. Concurrently, sustainable agricultural practices, including agroforestry, conservation agriculture, and water harvesting techniques, are promoted to enhance farm productivity and diversify livelihood options for farmers. Moreover, watershed development programs prioritize community involvement and capacity building, fostering local ownership and empowerment. This abstract elucidates the multifaceted benefits of watershed development in revamping rainfed farming systems, emphasizing its potential to mitigate environmental degradation, enhance agricultural resilience, and improve rural livelihoods.

Authors: Odion Clement , Kpolugbo James , Dongo Andrew E. , Ogbetere Friday Emeakpor 
Published: July 2024

Background: Acute appendicitis is a common surgical condition of the abdomen. However, diagnostic difficulties may arise, resulting in high rate of negative appendicectomies.
This study aimed to assess the role of C-reactive protein (CRP) in improving the accuracy of diagnosis of acute appendicitis and thus reducing the rate of negative appendicectomies.
Materials and Method: The study was a cross-sectional, hospital-based study carried out on 66 patients who had appendicectomy following a clinical diagnosis of acute appendicitis. Samples for CRP were collected from all recruited patients preoperatively. Following appendicectomy, the appendix was sent for histology. A proforma was used to collect data. All the statistical analyses were performed using IBM statistics package for social sciences (SPSS) version 21. At 95% confidence level, p-values less than 0.05 were considered significant.
Results: Thirteen (13) of the appendices removed had normal histopathologic examination, giving a negative appendicectomy rate of 19.7%. The diagnostic accuracy, sensitivity, specificity and positive predictive value for preoperative CRP were 80%, 79%, 85% and 95% respectively.
Conclusion: An elevated level of CRP is a useful aid for the diagnosis of acute appendicitis. Deferring surgery in patients with normal CRP would likely decrease the incidence of negative appendicectomies.

Profiling Protein Methylation with Cofactor Analog Containing Terminal Alkyne Functionality
Authors: Blum Gil , Bothwell Ian R. , Islam Kabirul , Luo Minkui 
Published: March 2013

AbstractEnzymatic transmethylation from the cofactor S‐adenosyl‐L‐methionine (SAM) to biological molecules has recently garnered increased attention because of the diversity of possible substrates and implications in normal biology and diseases. To reveal the substrates of protein methyltransferases (PMTs), the present article focuses on an alkyne‐containing SAM mimic, Se‐adenosyl‐L‐selenomethionine (ProSeAM), and a cleavable azido‐azo‐biotin probe to profile the targets of endogenous PMTs in cellular contexts. This article describes the stepwise preparation of cell lysates containing active, endogenous PMTs and subsequent target labeling with ProSeAM. The article continues with the enrichment of the ProSeAM‐labeled proteins with the azido‐azo biotin probe as a pulldown reagent and the subsequent reductive elution with sodium dithionate for proteomic analysis. The protocols provided here were formulated for ProSeAM as a profiling reagent but can be applied to other terminal‐alkyne‐containing SAM analog cofactors. Curr. Protoc. Chem.

Abstract
Emotional and motivational dysfunctions observed in Parkinson’s disease, schizophrenia, and drug addiction are associated to an alteration of the mesocortical and mesolimbic dopaminergic pathways, which include axons projecting to the prefrontal cortex, the ventral striatum, and the amygdala. Subpopulations of catecholaminergic neurons have been described in the cortex and striatum of several mammals, but the presence of such cells in the adult amygdala is unclear in murine rodents, and in other rodents appears to show variations depending on the species. Moreover, the embryonic origin of telencephalic tyrosine hydroxylase (TH) cells is unknown, which is essential for trying to understand aspects of their evolution, distribution and function. Herein we investigated the expression of TH mRNA and protein in cells of the striatum and amygdala of developing and adult mice, and analyzed the embryonic origin of such cells using in vitro migration assays. Our results showed the presence of TH mRNA and protein expressing cells in the striatum (including nucleus accumbens), central and medial extended amygdala during development, which are persistent in adulthood although they are less numerous, generally show weak mRNA expression, and some appear to lack the protein. Fate mapping analysis showed that these cells include at least two subpopulations with different embryonic origin in either the commissural preoptic area of the subpallium or the supraopto-paraventricular domain of the alar hypothalamus. These data are important for future studies trying to understand the role of catecholamines in modulation of emotion, motivation, and reward.
