Abstract	Wearable electronic textiles (e‐textiles) have emerged as a transformative technology revolutionizing healthcare monitoring and communication by seamlessly integrating with the human body. However, their practical application has been limited by the lack of compatible and sustainable power sources. Various energy sources, including solar, thermal, mechanical, and wind, have been explored for harvesting, leading to diverse energy harvesting technologies, such as photovoltaic, thermoelectric, piezoelectric, and triboelectric systems. Notably, 2D materials have gained significant attention as attractive candidates for energy harvesting and storage in e‐textiles due to their unique properties, such as high surface‐to‐volume ratio, mechanical strength, and electrical conductivity. Textile‐based energy harvesters employing 2D materials offer promising solutions for powering next‐generation smart and wearable devices integrated into clothing. This comprehensive review explores the utilization of 2D materials in textile‐based energy harvesters, covering their preparation, fabrication, and characterization strategies. Recent advancements are highlighted, focusing on the integration of 2D materials and their practical implementations, shedding light on the performance and effectiveness of 2D‐material‐based energy harvesters in e‐textiles, and highlighting their potential as a sustainable alternative to conventional power supplies in wearable technologies.

Abstract	In recent years, the biological synthesis of silver nanoparticles has captured researchers’ attention due to their unique chemical, physical and biological properties. In this study, we report an efficient, nonhazardous, and eco-friendly method for the production of antibacterial silver/silver chloride nanoparticles utilizing the leaf extract of Stachys emodi . The synthesis of se-Ag/AgClNPs was confirmed using UV-visible spectroscopy, DPPH free radical scavenging activity, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). An intense peak absorbance was observed at 437 nm from the UV-visible analysis. The Stachys emodi extract showed the highest DPPH scavenging activity (89.4%). FTIR analysis detected various bands that indicated the presence of important functional groups. The SEM morphological study revealed spherical-shaped nanoparticles having a size ranging from 20 to 70 nm. The XRD pattern showed the formation of a spherical crystal of NPs. The antibacterial activity performed against Erwinia carotovora showed the maximum inhibition by centrifuged silver nanoparticles alone (se-Ag/AgClNPs) and in combination with leaf extract (se-Ag/AgClNPs + LE) and leaf extract (LE) of 98%, 93%, and 62% respectively. These findings suggested that biosynthesized NPs can be used to control plant pathogens effectively.

Abstract	Zinc (Zn) deficiency in soil is an important restriction for the production of crops and a well-known human health issue. In semi-arid and arid regions of the world, deficiency of zinc is very common due to an increase in fixation and decrease in solubility. Zinc deficiency is a growing health concern, with 20.6% of children having zinc concentrations below 60 g/dL. Geographically there is a very close relationship between zinc deficiency in soil and humans which represents the soaring necessity for zinc biofortification in crops. Zinc biofortification of crops can be a cost-effective and long-term strategy for combating zinc insufficiency and preventing morbidity in the target population. The use of organic amendments is very good to overcome this problem by increasing the process of nutrient delivery and improving crop growth and productivity. Food crops that have been biofortified, including grains, beans, vegetables, and fruits, can provide enough micronutrients for the target population. Aside from the challenges, biofortified crops have a promising future in combating hunger.

Abstract	The Maillard reaction (MR) has been established to be a paramount contributor to the characteristic sensory property of thermally processed food products. Meanwhile, MR also gives rise to myriads of harmful byproducts (HMPs) (e.g., advanced glycation end products (AGEs) and acrylamide). Nutritional additives have attracted increasing attention in recent years owing to their potential to simultaneously improve nutritional quality and attenuate HMP formation. In this manuscript, a brief overview of various nutritional additives (vitamins, minerals, fatty acids, amino acids, dietary fibers, and miscellaneous micronutrients) in heat-processed food is provided, followed by a summary of the formation mechanisms of AGEs and acrylamide highlighting the potential crosstalk between them. The main body of the manuscript is on the capability of nutritional additives to modulate AGE and acrylamide formation besides their traditional roles as nutritional enhancers. Finally, limitations/concerns associated with their use to attenuate dietary exposure to HMPs and future perspectives are discussed. Literature data support that through careful control of the addition levels, certain nutritional additives possess promising potential for simultaneous improvement of nutritional value and reduction of AGE and acrylamide content via multiple action mechanisms. Nonetheless, there are some major concerns that may limit their wide applications for achieving such dual functions, including influence on sensory properties of food products, potential overestimation of nutrition enhancement, and introduction of hazardous alternative reaction products or derivatives. These could be overcome through comprehensive assay of dose-response relationships and systematic evaluation of the diverse combinations from the same and/or different categories of nutritional additives to establish synergistic mixtures.

Abstract	The time when the world is dealing with corona disaster, there is this fear that we might not forget about other communicable diseases. There are multiple international and national programs in place to prevent these communicable diseases. The fear is these programs might not get the attention it deserves at the time when all the attention is toward Covid-19. Currently more than 180 countries/regions have reported Covid-19 cases.1 The highly contagious measles cases have continued to increase. World Health Organization (WHO) data shows that globally measles cases rose by 300 percent in the first three months of 2019, compared to the same time period of 2018. The WHO African region has recorded a 700% increase, the Region of the Americas 60%, the European region 300%, the Eastern Mediterranean 100%, with 40% increases in Southeast Asia and the Western Pacific. According to statistics, it caused approximately 110,000 deaths worldwide in 2017.1,2 The point of concern is that even countries with high overall vaccination coverage like USA and Israel noted spikes in cases. United States recorded 1,282 individual cases of measles, greatest number since 1992.3 Speaking about polio, countries are still struggling with its eradication. Afghanistan, Nigeria and Pakistan are still endemic recording total of 29, 18 and 146 cases respectively in 2019.4 These are the countries currently dealing with the COVD-19 pandemic too. As of March 15, 2020, the Khyber Pakhtunkhwa Province of Pakistan reported 13 new circulating vaccine derived poliovirus (cVDP2) cases, the largest number of cases the province has ever seen in a day.5 According to WHO, Lower respiratory tract infections remained the deadliest communicable disease, causing 3.0 million deaths globally in 2016. Diarrheal diseases caused 1.4 million deaths in 2016. Similarly, Tuberculosis (TB) was responsible for 1.3 million deaths globally. Lower respiratory tract infections, Diarrhea diseases and Tuberculosis are among the top ten global causes of deaths. The situation at hand demands extra measures on the part of authorities and public health experts. With the Covid-19 pandemic, trend has been observed where there is diversion of all human and budgetary resources toward Covid -19 pandemic. This pandemic and helplessness of many nations to deal with it alarms us that we are not capable of dealing with another pandemic at this time. Therefore, it is important that all those programs i.e. Immunization programs, TB, HIV, Hepatitis control programs etc. must continue at the same time. Otherwise, more deaths might result associated with these communicable diseases than the overall endeavor would save from Covid -19.

Abstract	This paper aimed to evaluate the effects of ultrasound-assisted L-histidine marination (UMH) on meat quality and actomyosin properties of beef M. semitendinosus. Our results found that UMH treatment effectively avoided excessive liquid withdrawal, and disrupted myofibril integrity by modifying the water distribution and weakening connection of actin-myosin with increased muscle pH. The ultrasound-treated sample provided more opportunity for the filtration of L-histidine to intervene the isoelectric point and conformation of muscle protein. The activated caspase-3 and changes of ATPase activity in UMH-treated meat accelerated the postmortem ageing, and L-histidine might competitively inhibit the actin-myosin binding by the imidazole group. UMH decreased the surface hydrophobicity by shielding hydrophobic area and unfolding the actomyosin structure. In addition, the increased actomyosin solubility with smaller particle size enhanced the SH content for better cross-linking of myosin tail, and formation of heat-set gelling protein structure. Therefore, UMH treatment manifested the potential to improve beef quality.

Abstract	In many areas of developing countries, agriculture soil is irrigated with water from drains contaminated with industrial wastewater that contains many toxic substances including arsenic. Such sites could be explored for arsenic-resistant plant growth-promoting microbes. Ten arsenic-resistant bacteria were isolated from such a site and were characterized. Their ability to resist and reduce/oxidize arsenic was determined. The bacteria were also analyzed for plant growth-promoting abilities such as auxin and hydrogen cyanide production, phosphate solubilization, and nitrogen fixation. The effect of these bacteria on plant growth was determined using Vigna radiata both in presence and absence of arsenic. Bacterial isolates S254 and S255 showed maximum resistance against arsenic; up to 225 mM of As(V) and 25 mM of As(III). The phylogenetic analysis revealed that strain S254 belonged to the species Pseudoxanthomonas mexicana and strain S255 belonged to the species Stenotrophomonas maltophilia . Both P. mexicana S254 and S. maltophilia S255 showed positive results for hydrogen cyanide production, auxin production, and nitrogen fixation. P. mexicana S254 produced auxin at a concentration of 14.15 µg mL −1 and S. maltophilia S255 produced auxin as high as 68.75 µg mL −1 . Both the bacteria-enhanced the growth of V. radiata and a statistically significant increase in shoot and root lengths was observed both in the presence and absence of arsenic. The application of such bacteria could be helpful for the growth of plants in arsenic-contaminated lands.
