Abstract	Purpose: The prevalence of dry eye disease (DED) is rising among visual display terminal (VDT) users, a trend that correlates with the growing use of digital devices. The prevalence of VDT-associated DED is reported based on dry eye questionnaires; however, VDT's impact on tear film parameters is less understood. Methods: A review of published literature on both the alterations in tear film observed in VDT users and the impact of various interventions on their tear film. Results: Most studies show reduction in tear stability as well as reduction in the blink rate. The role of lacrimal gland hypofunction in visual display terminal (VDT) users is a subject of ongoing debate. Schirmer test values typically exceed the 10 mm threshold, suggesting normal tear production, and tear osmolarity remains within normal ranges but VDT users consistently present with lower Schirmer values compared to non-VDT users. The effects on Meibomian glands and mucin levels need more research as the numbers studied are small. Very few studies have analysed mucin levels in VDT users with reports of normal or reduced values. Even asymptomatic users can have tear film instability; hence, the diagnostic criteria need to be formulated and validated. Different interventions such as neurostimulation, blink improving apps, eyelid warming devices, moist goggles, and lubricants have been explored in VDT users but without a control arm and in asymptomatic VDT users in most studies. Conclusion: The alterations have been observed on aqueous, lipid and mucin components of the tear film, although the extent of the impact is variable across studies. There is urgent need of well-designed studies for studying the tear film changes and management options for the upcoming lifestyle epidemic in VDT users.

Abstract	Background: Calcium oxalate monohydrate (COM) forms the most common type of kidney stones observed in clinics, elevated levels of urinary oxalate being the principal risk factor for such an etiology. The objective of the present study was to evaluate the anti-nephrolithiatic effect of herbo-mineral formulation, Lithom. Methods: The Results: The presence of Lithom during COM crystals synthesis significantly reduced the average crystal area, feret's diameter, and area-perimeter ratio, in a dose-dependent manner. SEM analysis revealed that COM crystals synthesized in the presence of 100 and 300 μg/mL of Lithom exhibited a veritable morphological transition from irregular polygons with sharp edges to smoothened smaller cuboid polygons. UHPLC analysis of Lithom revealed the presence of Trigonelline, Bergenin, Xanthosine, Adenosine, Bohoervinone B, Vanillic acid, and Ellagic acid as key phytoconstituents. In EG-induced SD rats, the Lithom-treated group showed a decrease in elevated urinary oxalate levels, oxidative stress, and renal inflammation. Von Kossa staining of kidney tissue also exhibited a marked reduction in crystal depositions in Lithom-treated groups. Conclusion: Taken together, Lithom could be a potential clinical-therapeutic alternative for management of nephrolithiasis.

Abstract	Transgalactosylation reaction is the penultimate step in the production of galactooligosaccharides (GOSs) which has prominent applications in the treatment of disorders. In the present study, partially purified β-galactosidase from Enterobacter aerogenes KCTC2190 was used for the synthesis of prebiotic GOSs. GOSs were produced using lactose as substrate. Structural elucidation of collected fractions of GOSs by liquid chromatography electrospray ionization mass spectrometry exhibited the appearance of major peaks of produced GOSs at m/z 241.20, 481.39, 365.11, 527.17, and 701.51 respectively. GOSs facilitated the growth of potential probiotic strains (Lactobacillus delbrueckii ssp. helveticus, Bifidobacterium bifidum, and Lactiplantibacillus plantarum) and liberated propionate and butyrate as principal short-chain fatty acids which established its prebiotic potency. Synbiotic combinations exhibited good antioxidant activities. Synbiotic combinations also exhibited antimicrobial activities against pathogenic microorganisms namely Staphylococcus aureus and Escherichia coli. Synbiotic combinations of GOSs and the respective probiotic microorganisms were able to decrease viable human bone cancer cells (MG-63).

Abstract	In the present study, Enterobacter aerogenes KCTC2190 was isolated from soil around a cattle shed area, which was capable of producing intracellular β-galactosidase. Partially purified β-galactosidase was immobilized by entrapment method in agar-agar gel matrix. Agar-agar entrapped beads were prepared by dropping the enzyme-agar solution to ice-cooled toluene-chloroform ((3:1 (v/v)). 45.88±0.11% activity of partially purified β-galactosidase was retained after immobilization (bead shape). Maximum immobilization yield was observed in the presence of 2.5% agar-agar concentration. After immobilization, optimum temperature required for the enzyme-substrate reaction was shifted from 50 to 60 °C and the optimum reaction time was shifted from 15 to 25 min. The optimum pH for both free and immobilized β-galactosidase was pH 7. Free enzyme showed lower activation energy in comparison with the immobilized one. For free as well as immobilized β-galactosidase thermal deactivation, rate constant (k

Abstract	Discotic liquid crystals (DLCs) are widely acknowledged as a class of organic semiconductors that can harmonize charge carrier mobility and device processability through supramolecular self-assembly. In spite of circumventing such a major challenge in fabricating low-cost charge transport layers, DLC-based hole transport layers (HTLs) have remained elusive in modern organo-electronics. In this work, a minimalistic design strategy is envisioned to effectuate a cyanovinylene-integrated pyrene-based discotic liquid crystal (PY-DLC) with a room-temperature columnar hexagonal mesophase and narrow bandgap for efficient semiconducting behavior. Adequately combined photophysical, electrochemical, and theoretical studies investigate the structure-property relations, logically correlating them with efficient hole transport. With a low reorganization energy of 0.2 eV, PY-DLC exhibits superior charge extraction ability from the contact electrodes at low values of applied voltage, achieving an electrical conductivity of 3.22 × 10

Abstract	The global repercussions of coronavirus disease 2019 (COVID-19) include substantial worldwide mortality and have brought to light existing gaps in healthcare systems. Particularly, diseases requiring time-sensitive treatment, such as ST-elevation myocardial infarction (STEMI), have faced significant challenges due to the impact and revelations of the COVID-19 pandemic on healthcare infrastructure. This review addresses the impact of the pandemic on STEMI, exploring incidence, treatment modalities, and clinical outcomes. Through a critical examination of existing literature, the intricate relationship between the pandemic and cardiovascular health, specifically STEMI, is elucidated. The COVID-19 pandemic has had a significant impact on the management of STEMI, with changes in hospitalization rates, treatment strategies, and the presentation of the disease posing significant challenges. The contradictory results of COVID-19 and post-vaccine myocardial infarction, as well as gender differences in reported cases, highlight the need for further research to clarify these relationships.

Abstract	In the present study, Enterobacter aerogenes KCTC2190 was isolated from soil around a cattle shed area, which was capable of producing intracellular β-galactosidase. Partially purified β-galactosidase was immobilized by entrapment method in agar-agar gel matrix. Agar-agar entrapped beads were prepared by dropping the enzyme-agar solution to ice-cooled toluene-chloroform ((3:1 (v/v)). 45.88±0.11% activity of partially purified β-galactosidase was retained after immobilization (bead shape). Maximum immobilization yield was observed in the presence of 2.5% agar-agar concentration. After immobilization, optimum temperature required for the enzyme-substrate reaction was shifted from 50 to 60 °C and the optimum reaction time was shifted from 15 to 25 min. The optimum pH for both free and immobilized β-galactosidase was pH 7. Free enzyme showed lower activation energy in comparison with the immobilized one. For free as well as immobilized β-galactosidase thermal deactivation, rate constant (kd) increased with increasing temperature while the values of decimal reduction time (D-values) and half-lives (t₁/₂) decreased. Immobilization process increased the t₁/₂ and D-values of β-galactosidase while it decreased the kd. Thermostability of immobilized β-galactosidase was higher as they showed higher enthalpy (ΔΗ⁰) and Gibb’s free energy (ΔG⁰)value than those of the free β-galactosidase. The negative entropy (ΔS⁰) of free and immobilized β-galactosidase established that both were in a more ordered state within the temperature range (50 to 70 °C) studied. Immobilized β-galactosidase was able to retain 51.65±1.61% of its initial activity after 7 batches of enzyme-substrate reaction. Immobilized β-galactosidase showed 78.09±3.69% of its initial activity even after 40 days of storage at 4 °C.
