    Abstract The inappropriate and inconsistent use of antibiotics in combating multidrug-resistant bacteria exacerbates their drug resistance through a few distinct pathways. Firstly, these bacteria can accumulate multiple genes, each conferring resistance to a specific drug, within a single cell. This accumulation usually takes place on resistance plasmids (R). Secondly, multidrug resistance can arise from the heightened expression of genes encoding multidrug efflux pumps, which expel a broad spectrum of drugs from the bacterial cells. Additionally, bacteria can also eliminate or destroy antibiotic molecules by modifying enzymes or cell walls and removing porins. A significant limitation of traditional multidrug therapy lies in its inability to guarantee the simultaneous delivery of various drug molecules to a specific bacterial cell, thereby fostering incremental drug resistance in either of these paths. Consequently, this approach prolongs the treatment duration. Rather than using a biologically unimportant coformer in forming cocrystals, another drug molecule can be selected either for protecting another drug molecule or, can be selected for its complementary activities to kill a bacteria cell synergistically. The development of a multidrug cocrystal not only improves tabletability and plasticity but also enables the simultaneous delivery of multiple drugs to a specific bacterial cell, philosophically perfecting multidrug therapy. By adhering to the fundamental tenets of multidrug therapy, the synergistic effects of these drug molecules can effectively eradicate bacteria, even before they have the chance to develop resistance. This approach has the potential to shorten treatment periods, reduce costs, and mitigate drug resistance. Herein, four hypotheses are presented to create complementary drug cocrystals capable of simultaneously reaching bacterial cells, effectively destroying them before multidrug resistance can develop. The ongoing surge in the development of novel drugs provides another opportunity in the fight against bacteria that are constantly gaining resistance to existing treatments. This endeavour holds the potential to combat a wide array of multidrug-resistant bacteria.

    Abstract Bacteria cells exhibit multidrug resistance in one of two ways: by raising the genetic expression of multidrug efflux pumps or by accumulating several drug-resistant components in many genes. Multidrug-resistive tuberculosis bacteria are treated by multidrug therapy, where a few certain antibacterial drugs are administered together to kill a bacterium jointly. A major drawback of conventional multidrug therapy is that the administration never ensures the reaching of different drug molecules to a particular bacterium cell at the same time, which promotes growing drug resistivity step-wise. As a result, it enhances the treatment time. With additional tabletability and plasticity, the formation of a cocrystal of multidrug can ensure administrating the multidrug chemically together to a target bacterium cell. With properly maintaining the basic philosophy of multidrug therapy here, the synergistic effects of drug molecules can ensure killing the bacteria, even before getting the option to raise the drug resistance against them. This can minimize the treatment span, expenditure and drug resistance. A potential threat of epidemic from tuberculosis has appeared after the Covid-19 outbreak. An unwanted loop of finding molecules with the potential to kill tuberculosis, getting their corresponding drug approvals, and abandoning the drug after facing drug resistance can be suppressed here. This perspective aims to develop the universal drug regimen by postulating the principles of drug molecule selection, cocrystallization, and subsequent harmonisation within a short period to address multidrug-resistant bacteria.

    Abstract Physical injuries in sports are unavoidable, but they can be mitigated and even treated by using molecular hydrogen, which can be administered via a specially formulated sunscreen. The photocatalysts are a special class of semiconductors that can absorb a specific spectrum of light to promote its electron from the valance band (VB) to the conduction band (CB). This creates positively charged holes at VB and negatively charged electrons at CB in generating photochemical reaction centres. Once a photocatalyst that absorbs a harmful UV band from sunlight and can split water is doped inside a hydrogel will produce hydrogen in the presence of sunlight. If we employ such photocatalyst-doped hydrogel over naked skin, the hydrogel will act as a continuous source of water, which will absorb water from sweet, store it inside the hydrogel matrix and deliver it to the photocatalyst for splitting it further into the hydrogen. As a result, such photocatalyst-doped hydrogel can be used as a sunscreen to protect against sunlight and can use that spectrum of light for producing hydrogen from sweat continuously. Hydrogen can be absorbed through the skin and diffused in the body to heal wound-prone or injured muscles, and nerves. Because hydrogen may travel throughout the body, the catalyst-doped hydrogel can be used as a topical gel to treat various ailments such as muscle-nerve skin injuries, cancer, Parkinson's disease, and others. Besides common people, even athletes can use it as sunscreen during sports, which is not feasible for other hydrogen administrating systems.

    Abstract Introduction: Harvesting peroneus longus for ACL reconstruction is thought to create ankle instability which could add to postural instability from an ACL injury. This apprehension prevents its use as a graft of primary choice for many surgeons. To date, there is no evidence available describing changes in postural control after its use in ACL reconstruction. The purpose of the study was to analyse the changes in postural control in the form of static and dynamic body balance after ACL reconstruction with Peroneus Longus Tendon Graft and compare it with the unaffected limb at different time intervals.
    Materials and methods: Thirty-one participants with ACL injury were selected and subjected to an assessment of static and dynamic balance before and after ACL reconstruction using the HUMAC balance system. Outcome measures for Centre of Pressure (COP) assessment were average velocity, path length, stability score, and time on target. Comparison of scores was done pre-operatively as well as at three- and six-months post-reconstruction with Peroneus longus tendon graft.
    Results: Static balance of the affected limb showed significant improvement with a decrease in average velocity (F=4.522, p=0.026), path length (F=4.592: p=0.024) and improvement of stability score (F=8.283, p=0.001). Dynamic balance measured by the time on the target variable also showed significant improvement at six-month follow-up (F=10.497: p=0.000). There was no significant difference between the affected and non-affected limb when compared at the different time intervals.
    Conclusion: The static and dynamic balance, which is impaired after ACL injury, improves with ACL reconstruction with PLT autologous graft. Hence PLTG can be safely used as a graft for ACL reconstruction without affecting postural control and body balance.

    Abstract Sensing of gaseous environment pollutants and health hazards is in demand these days and in this regard, lethal phosgene has emerged as a leading entrant. In this contribution, we have successfully developed a facile chemodosimeter (ANO) based on an anthracene fluorophore and oxime recognition site with an interesting mechanism to sense lethal phosgene evolved from bleaching powder, a very popular disinfectant and sanitizer. The ANO probe is highly competent in recognizing deadly phosgene in solution and in the gaseous phase with a detection limit in the nanomolar range (1.52 nM). The sensing mechanism is confirmed by UV-vis, emission spectroscopy, mass spectrometry, and computational studies.

    Abstract Hemophilia, cancer, diabetes, cardiovascular disease, mental health issues, immunological deficiencies, neuromuscular disease, blindness, and other ailments can all be treated with gene silencing and gene therapy, a growing discipline in medicine. It typically refers to a range of therapeutic techniques in which a patient's body's particular cells are given genetic material designed to correct and erase genetic flaws. The advancements in genetics and bioengineering have paved the way for the conceptualization of gene therapy through the manipulation of vectors, enabling the targeted transfer of extrachromosomal material to specific cells. One of the main focus areas of this methodology is the escalation of delivery vehicles (vectors), primarily plasmids or viruses; it still has difficulties because there is no good delivery mechanism that can precisely deliver stable small interfering Ribonucleic Acid (siRNA) or DNA to the target tissue location. As they are non-fluorescent, the siRNA or DNA delivery procedure is unable to be monitored by these carriers. In the context of quantum dots (QDs), the formation of QD-siRNA or QD/DNA complexes facilitated the real-time monitoring and precise localization of QDs during the silencing, delivery, and transfection processes. The unique dual-modality optical and fluorescent properties exhibited by quantum dots contribute to their utility as versatile imaging probes. The research studies discussed in this review article will provide a framework for designing efficient QD-based nanocarriers that can successfully carry therapeutic genetic tools into targeted cells. As a result of their findings, the researchers developed some unique QDs that successfully attached to the siRNA or DNA and carried it to the desired place. The use of these QD-based delivery devices could enhance the field of gene silencing and gene delivery.

    Abstract Indolamines (e.g., serotonin and melatonin) are tryptophan-derived class of neurotransmitters and neuromodulators that play crucial roles in mood regulation, sleep-wake cycles, and gastrointestinal functions. These biogenic amines exert their effects by binding to specific receptors in the central nervous system, influencing neuronal activity and signalling cascades. Indolamines are vital in maintaining homeostasis, and imbalances in their levels have been implicated in various neurological and psychiatric disorders. Hence, in the present study, we have investigated the nonlinear properties of indolamines under a continuous wave (CW) and pulsed laser excitation using the closed-aperture (CA) Z-scan technique. The CA Z-scan is a cost-effective and sensitive analytical tool for investigating nonlinear properties. It is observed that indolamines show negative refractive and positive absorptive nonlinearity under in vitro physiological conditions. The origin of nonlinearity is ascribed to the thermo-optical effect governed by the saturated atomic absorption and molecular orientation mechanisms under CW and pulsed laser excitation, respectively. The strength of nonlinearity is found to vary linearly with the concentration of indolamines. Overall, serotonin possesses stronger nonlinearity than melatonin. The maximum nonlinearity (refractive index (n
