The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron versions have been the sole one circulating for quite some time. Subvariants BA.1, BA.2, BA.3, BA.4, and BA.5 of the Omicron emerged over time and through mutation, with BA.1 responsible for the most severe global pandemic between December 2021 and January 2022. Other Omicron subvariants such as BQ.1, BQ.1.1, BA.4.6, BF.7, BA.2.75.2, XBB.1 appeared recently and could cause a new wave of increased cases amid the ongoing COVID-19 pandemic. There is evidence that certain Omicron subvariants have increased transmissibility, extra spike mutations, and ability to overcome protective effects of COVID-19 neutralizing antibodies through immunological evasion. In recent months, the Omicron BF.7 subvariant has been in the news due to its spread in China and a small number of other countries, raising concerns about a possible rebound in COVID-19 cases. More recently, the Omicron XBB.1.5 subvariant has captured international attention due to an increase in cases in the United States. As a highly transmissible sublineage of Omicron BA.5, as well as having a shorter incubation time and the potential to reinfect or infect immune population, BF.7 has stronger infection ability. It appears that the regional immunological landscape is affected by the amount and timing of previous Omicron waves, as well as the COVID-19 vaccination coverage, which in turn determines whether the increased immune escape of BF.7 and XBB.1.5 subvariants is sufficient to drive new infection waves. Expanding our understanding of the transmission and efficacy of vaccines, immunotherapeutics, and antiviral drugs against newly emerging Omicron subvariants and lineages, as well as bolstering genomic facilities for tracking their spread and maintaining a constant vigilance, and shedding more light on their evolution and mutational events, would help in the development of effective mitigation strategies. Importantly, reducing the occurrence of mutations and recombination in the virus can be aided by bolstering One health approach and emphasizing its significance in combating zoonosis and reversal zoonosis linked with COVID-19. This article provides a brief overview on Omicron variant, its recently emerging lineages and subvairants with a special focus on BF.7 and XBB.1.5 as much more infectious and highly transmissible variations that may once again threaten a sharp increase in COVID-19 cases globally amid the currently ongoing pandemic, along with presenting salient mitigation measures.

Authors: Goyal Rajat , Chandran Deepak , Garg Kajal , Mohankumar Pran , Gupta Sumeet , Gautam Rupesh K. , Chopra Hitesh , Dhama Kuldeep
Published: January 2023

Sexuality has become a medical issue in the context of aging due to a variety of aspects, such as growing life expectancy, an optimistic societal paradigm that indorses sexuality as significant for the superiority of life with age, and the medicalization of sexuality with the emergence of remedial medicines to extravagance sexual dysfunction. At any age, a reduction in the desire for sexual activity or inadequate performance of sexual intercourse is considered atypical and requires a medicinal treatment response. However, despite concerns that this is leading to an unhealthy obsession with sexuality from a medical perspective, this line of thinking is likely to continue. In this context, people can identify and take advantage of sexual problems. Sexual desire and performance are affected by normal physiological changes associated with aging in both genders. Medical experts must understand these changes to optimize sexual functioning in older patients. Sexual health can only be improved by addressing both sexual rights and enjoyment, even in the current politically charged context. Through legislation, programming, and lobbying, we may all work to enhance health, happiness, and quality of life by fostering more positive associations between sexual health, sexual rights, and sexual pleasure. This calls for not just a thorough understanding of the real-world consequences of these ideas' interconnectivity, but also conceptual, individual, and systemic approaches that properly acknowledge and alleviate the problems imposed on people's lives due to insufficient consideration of these links. This review describes the factors associated with aging and sexuality, the normalization and medicalization of sexual health, and unusual situations associated with aging, including institutionalized care and the prospects of elder abuse.

The recirculatory aquaculture system makes it possible to multiply fish production while consuming fewer resources. Essential factors of this technology include higher yield, safety, and water management. In addition, the scope of potential future research in hydroponics and aquaponics has been discussed. Furthermore, the paper identifies and discusses the various applications of hydroponics and aquaponics in agriculture.
Removal of Lead from Aqueous Solution by Fusarium oxysporum: Equilibrium and Phytotoxicity Studies
Authors: Kapoor Riti Thapar
Published: January 2023

Lead is a toxic metal of public health concern. The applicability of Fusarium oxysporum biomass as a biosorbent for the removal of lead ions from wastewater is assessed in the present investigation. Batch experiments were conducted under different experimental conditions for analysis of the lead biosorption capacity of live and dead biomass of Fusarium oxysporum. Lead ions were significantly absorbed at pH 5 with a 2g adsorbent amount at 300C. Equilibrium results were analyzed by Langmuir and Freundlich isotherms and found that Langmuir isotherm is the best fit under this condition. A phytotoxicity study revealed that the growth parameters of wheat seeds were significantly increased in the lead solution treated with dead biomass as compared to the live biomass of F. oxysporum. Further, dead F. oxysporum significantly removed lead within 3 hours whereas live fungal biomass took two days for the complete removal of lead. Therefore, the results of the study suggested that live and dead biomass of F. oxysporum can be used as an effective, safe, and economically feasible sorbent for the removal of lead present in industrial effluent or wastewater systems.
Antifertility Potential of n-Butanol and Ethyl Acetate Extracts of Penicillium oxalicum OM282858 in Male Albino Rats as Biological Control Agents
Authors: Taha Ayat , A. Gouda Shaymaa
Published: January 2023

Rodents cause significant damage to many crops, spread diseases, and pose a severe risk to public health. Several synthetic contraceptive agents are available for controlling rodents; however, their use is associated with toxic effects on non-target organisms. Penicillium oxalicum has several medical properties, but no reports were available on fertility. This study aimed to assess the antifertility potential of n-butanol and ethyl acetate extracts of P. oxalicum in adult male albino rats as biological control agents by lowering the population size of rodent pests. Rats were assigned into three groups (n = 36). The first control group (GI) was injected intraperitoneally with 0.5% dimethyl sulfoxide (DMSO). The second (GII) and third (GIII) groups were injected with a single dose of 200 mg/kg body weight (b.wt.) of n-butanol and ethyl acetate extracts of P. oxalicum intraperitoneally, respectively, after dissolving in 0.5% DMSO. Further, P. oxalicum was identified morphologically and molecularly and then submitted with accession number OM282858 to the National Center for Biotechnology Information (NCBI) GenBank. The antifertility potential of P. oxalicum was evaluated after 24 h (the injection period), 96 h, and 168 h (the recovery periods) of treatments. The effects of the treatments on organ weight, testicular histology, histomorphometry measurements, and sperm characteristics were assessed. Both P. oxalicum extracts caused changes in reproductive organ weights, testicular histology, histomorphometry measurements, and spermatogenic arrest accompanied by a significant decrease in the count of epididymal sperm and its motility and an increase in the percentage of sperm abnormalities during the injection and recovery periods. Thus, the results suggest that both P. oxalicum extract treatments cause suppression of fertility in adult male rats. Therefore, these outcomes are essential for public health, farming establishments, and vertebrate pest control managers.

Published: January 2023

The Upper Moulouya region, including the Mibladen (M) and Zaïda (Z) mines, is one of the highest lead (Pb) deposit areas in Morocco. These mines, abandoned without any measure of rehabilitation, constitute the main source of soil pollution by Metallic Trace Elements (MTEs) accumulation in the region. In this study, two greenhouse phytoremediation experiments (for the Mibladen and Zaida sites) were set up using Italian ryegrass (Lolium multiflorum) specie to assess its capacity and ability to remediate soils contaminated by zinc (Zn), cadmium (Cd), copper (Cu), and Pb. For both experiments, various factors including (i) three substrates (waste treatment [Wt]; clay uncovering [Cun]; and unpolluted control soil [Ucs]) and (ii) three treatments (no treatment, treatment with organic matter, and treatment with chemical fertilizers) were studied. The results before planting indicated that Wt substrates had poorer physicochemical properties than those of Cun, thus they are the most exposed to the degradation phenomena. This is confirmed by pollution index (PI) results that revealed the trend of PI (Z Wt)> PI (M wt)> PI (M Cun)> PI (Z Cun)> PI (Z Ucs)> PI (M Ucs). The results of experiments indicated that ryegrass crops can grow on substrates contaminated with MTEs. Depending on the applied fertilizers, available metals, and the type of soil, the phytoremediation results showed that L. multiflorum can tolerate, hyperaccumulate, and translocate MTEs from polluted substrates. Our findings suggest that this plant can be a solution for remediating alkaline soils polluted by Cd, Pb, Zn, and Cu in Mediterranean conditions.

Published: January 2023

Vitamin D (Vit D) has anticancer properties including activating cell senescence inhibiting cancer cell proliferation, inducing apoptotic cell death, and decreasing cancer cell migration. On the other hand, statins showed favorable anticancer activities including anti-survival, anti-proliferation, and anti-migration effects. The current study aimed to investigate the synergistic anticancer effect of Vit D and statins against HCC1937 triple-negative breast cancer cells. The antiproliferative effect was tested by MTT assay after 48 hours of the treatments. Trypan blue test and clonogenic assay were used to test the anti-survival activities of the treatments. The ability of the treatments to inhibit the migration ability was tested by scratch assay. Levels of the cell cycle and apoptotic markers were determined by western blotting. Results of the study revealed that all the tested compounds including Vit D, atorvastatin (Ator), simvastatin (Simv), and pitavastatin (Pita) inhibited HCC1937 breast cancer cell growth with different IC50 values ranging from 4.49-12.95 µM. Combined application of Pita and Vit D showed potent synergistic antiproliferative activities against HCC1937 breast cancer cells. The combined therapy of (1µM Vit D and 2 µM Pita) inhibited HCC1937 cell proliferation by cell cycle arrest and apoptosis as evidenced by increasing p21, p53, and cleaved PARP. Finally, the combined treatment decreased the p-STAT3 level in HCC1937 breast cancer cells. The results of the study can be concluded that the combined treatment of Pita and Vit D has a synergistic anticancer effect against HCC1937 breast cancer cells.

Published: January 2023

Synergism between various plant growth regulators is reported to be a key factor for the development of efficient in vitro propagation for any plant. Therefore, the current study examines the synergistic impact of plant growth regulators on in vitro propagation of Eclipta alba, an important medicinal plant possessing diverse medicinal properties. For the establishment of aseptic cultures, nodal segments were employed as explants on MS medium supplemented with 2.5 μM of 6-benzyle adenine (BA). Varying concentrations of BA and Kinetin (KIN)(0.0-5.0 μM), either alone or in combination with α- naphthalene acetic acid (NAA @ 0.0-5.0 μM) and indole 3-acetic acid (IAA@ 0.0-5.0 μM), were found to be effective for promoting shoot proliferation. Compared to KIN, BA was found to promote shoot proliferation and elongation more effectively. Further, the addition of 0.5μM NAA in the MS medium supplemented with 2.5 μM of BA increased shoot multiplication and elongation frequency from 58 and 17 percent to 65 and 21 percent respectively. The rooting frequency was found to be maximum on 1/2 strength MS medium supplemented with 5.0 μM of indole 3-butyric acid (IBA), which was found to be a superior auxin for inducing roots as compared to the NAA and IAA. With a 75% survival rate, in vitro raised plantlets were effectively acclimatized first in a poly house and later under greenhouse conditions. Molecular analysis was carried out using RAPD markers, with results indicating that the micropropagated plants were genetically identical to the mother plant. The developed micropropagation protocol for E. alba can be used at the commercial level for the mass multiplication of plants.

Published: January 2023

Agriculture is an essential sector for the increasing world population, hence the need for more food production.  However, the aim of increasing food crop production is mostly suppressed by abiotic stresses such as drought and salinity. Salinity is a major limiting factor that inhibits the potential of plant growth and productivity worldwide. Hence, understanding the mechanisms behind plant stress response is important for developing new biomarker approaches that will increase salt tolerance in crops.  To survive, plants exhibit various morphological, physiological, and biochemical processes when faced with saline conditions. This study was carried out to explore and evaluate the morphological and physiological effects of salinity on maize grown in the absence/presence of NaCl, followed by measurement of the various growth parameters at the end of a treatment cycle.  Results of the study revealed that salt stress significantly decreased growth parameters such as plant height, leaf number, leaf width, leaf area, leaf length, and shoot (weight and length).  On the other hand, salinity decreased physiological traits such as stomatal count, stomatal density, transpiration, and respiration rates.  This study has shown the negative effects of salt stress on the morphology and physiology of maize.  These findings can be used as a reference tool in stress response studies focusing on salt stress pathways in maize and other related crops.
Impact of helpful reviews on customer purchase intention with special reference to mobile phone reviews
Authors: Rawat Kavita , Kumar Sunita
Published: January 2023

Technological advances in the digital space have provided renewed impetus to businesses. Costly, labor-intensive marketing campaigns have been replaced by digital marketing. However, along with benefits, the increasing sophistication and exponential growth of e-commerce businesses have also introduced new challenges. The large number of similar product offerings and the high volume of reviews have created a technology-induced hurdle for consumers that can impair their thought processes. Often, users will only scan the top few reviews to arrive at a decision. In the current setup, older reviews that accumulate votes over time are found at the top of the helpful review list, in contrast to fresh entrants. The current study proposes placing reviews in appropriate positions in the helpful review list using statistical and scientifically derived helpfulness scores. The study utilized a sample of consumer goods (specifically, mobile phones) and re-ranked reviews based on their expected score. Amazon.in provided the initial review dataset. Random Forest and gradient-boosting regression techniques were used to predict review helpfulness. An Elaboration Likelihood Model was used to explore the impact of central and peripheral cues on review helpfulness. The gradient-boosting regression was the best-performing method of predicting review helpfulness, and the reviews were re-ranked. The re-ranked reviews were tested for helpfulness vis-a-vis the initial ranking of reviews using the survey method. The result indicated that the proposed re-ranking of reviews was more helpful to end users and helped mitigate uncertainty in decisions. The study utilized the Information Acceptance Model to assess the influence of electronic word of mouth on purchase intention.

The literature has shown that emotional intelligence can control a person's rational decision-making and also contribute to mathematical problem-solving. There have been many correlational studies investigating the effect of emotional intelligence on the mathematical problem-solving abilities of students in Indonesia. This study aims to summarize the effect size values given by the primary study through meta-analysis techniques. Twenty-one primary studies that have been published by journal publishers, theses, and proceedings in the last ten years and meet the inclusion criteria will be analyzed. Data analysis using Jeffreys's Amazing Statistics Program (JASP) software with the stages of investigating publication bias, random or fixed effect models, and statistical hypothesis testing. Based on the random effects model, the results showed that there was a positive effect of emotional intelligence on students' mathematical problem-solving abilities in Indonesia with the category of medium positive effect (r = 0.6; p < 0.01). These results suggest for students and learners to give serious attention to students' emotional intelligence to improve their mathematical problem-solving abilities.   Keywords: Emotional Intelligence, Emotional Quotient, Mathematics Problem Solving, Meta-Analysis.

Landslides in Bengawan Solo Watershed can be caused by the increasing area of critical land and continuous process of erosion. Landslides vulnerability also caused by the condition of slope that are sloping to steep, soil textures which tends to smooth and deep regolith. It can affect the activity of the community around the watershed. This study aims to analyze the level of landslides vulnerability in Cemoro sub-watershed as part of the Bengawan Solo Watershed in order to reduce the impact of landslides by using Geographic Information System. Landslides vulnerability is determined by considering factors such as geological type, soil regolith depth, slope, fault and soil texture. Based on the result of landslides vulnerability analysis, the Cemoro sub watershed has two levels of landslides vulnerability which are a low level of 68,17% with 658,4 ha of area and a medium level of 31,83% with 307,35 ha of area. Results of this study is a map of landslides vulnerability which is used as a reference to improve mitigation in the Cemoro sub watershed using soil conservation.

Forest fire in Indonesia is a cataclysmic event that routinely happens consistently every year. The Indonesian government's intervention in suppressing forest fires is often carried out when massive fires have already occurred massively. When it happens in peat soil, forest fires become hard to extinguish because of the characteristics of burning below the ground surface, better known as the phenomenon of peat smoldering. Thus, that condition challenges the mitigation of forest fires in Indonesia to prioritize preventive principles in its implementation, one of which is through observing the physical condition of peatlands. This study examines and identifies existing regulations and policies concerning forest fires disaster mitigation by taking Riau Province as study area, one of Indonesia's areas that are, in many cases, hit by forest fires annually. Through the analysis of literature studies of relevant sources, this paper seeks to provide input on how monitoring the physical condition of peatlands can support decision-making related to forest fires disaster mitigation activities. This study explains that policies and regulations concerning the mitigation of forest fire in Indonesia still have not considered the scientific basis of the peatland physical parameters for mitigation activities, especially in determining disaster status level, which has further implications for the effectiveness of forest fires suppression activities. Furthermore, this study also highlights that by monitoring peatlands' physical condition, peatlands can be implemented to improve the paradigm in overcoming forest fires in Indonesia to be more preventive and succesful.

Published: January 2023

The increasing demand for energy in Indonesia is due to the need or the number of Indonesian population which has increased and is inversely proportional to the availability and production of existing energy. One of the best solutions that can be done is to promote the use of pioneer wood (fast growing plant) as an energy source by processing wood into wood pellets. The method used is a survey method by looking for a place to grow several types of pioneer plants. The purpose of this study was to determine the quality of wood pellets and the potential of several types of pioneer plants tested as environmentally friendly, sustainable renewable bioenergy. The pioneers tested were Acacia mangium, Jatropha curcas, Macaranga tanarius, Swietenia mahagoni, Leucaena leucocephala, and Sesbania grandiflora. The quality of Wood Pellets from pioneer plants is seen from the density ranging from 0.433 gr / cm3 to 0.503 gr / cm3, moisture content of 5.55% - 12.4%, ash content of 1.95-6.2%, and the calorific value of powder from 3657.67% - 4178.18%. Of the several types of pioneer plants tested, the most potential was Leucaena leucocephala because it had met SNI 8021 - 2014 and had the highest calorific value as required.
