N-glycosylation is a complex mechanism in which the carbohydrate molecules bind to the Asn amino acid in the N-glycan consensus sequence (AsnXxxThr/Ser sequon, where Xxx is any residue, excluding Pro). Introduction of additional N-linked glycosylation site into proposed location in the protein causes to its hyper-glycosylation and can enhance the protein characteristics to provide promising prospects in treatment. Glycoengineering is a favorably used strategy to design and generate hyper-glycosylated variants. In this research, human follicle-stimulating hormone (HuFSH) was considered to identify appropriate positions for adding novel N-glycan sites. A rational computational strategy was applied to predict functional/structural variations induced through changes in polypeptide chain. We analyzed the amino acid chain of FSH to find out the proper locations to introduce asparagine and/or threonine for creating novel N-glycan positions. This analysis resulted in the recognition of 40 possible N-glycosylation positions, and then the eight adequate ones were chosen for additional investigation. The model validation techniques were used to examine 3-dimensional structures of the chosen mutant proteins. Finally, 2 mutants with a further glycan site were recommended as eligible FSH hyper-glycosylated analogs, which may be regarded for subsequent experimental studies. Our in silico approach may decrease tedious and time-wasting laboratory researches of the mutants.Communicated by Ramaswamy H.

Several respiratory viruses co-circulate at one specific time. However, interface between different viruses has not been clearly established. This interaction is crucial to delineate, especially during pandemics, including the one relate to covid-19. This commentary will provide a brief description of how respiratory viruses interact and the outcome of this interaction on a pandemic.Communicated by Ramaswamy H. Sarma.
A gradual upward progression of blood pressure (BP) occurs regularly in most humans during aging. this website This is unfortunate, because it is generally recognized that elevation of BP, even when relatively mild, is eventually detrimental to human health. Accordingly, considerably more understanding of the pathophysiology behind such a phenomenon is important in order to institute the correct remedies. Two components of the ubiquitous metabolic syndrome (MS) with nutritional implications, elevated insulin resistance (IR) and excess body fat mass (FM), are often postulated to be critical driving forces behind the elevated BP that is common with aging. The current study, therefore, focuses on the presence and importance of IR and/or body FM in BP regulation of non-diabetics over the lifespan.

In cross sectional analyses, baseline data obtained from healthy, non-diabetic volunteers involved in prior clinical studies were analyzed by examining links between FBG measurements used as a surrogate for IR and body FM througorce behind BP regulation even in non-diabetics. FM influences BP substantially through its relationship with IR and also via other mechanisms directly linked to FM.This study reports the experimental and computational investigation on the binding of a common anticancer drug, gemcitabine, with the model plasma protein, bovine serum albumin (BSA). Several experimental and computational methods, such as intrinsic and synchronous fluorescence, UV-visible, and circular dichroism spectroscopies, consensus molecular docking and molecular dynamics simulation have been employed to elucidate the binding mechanism. Gemcitabine altered the UV-visible spectrum of BSA, which is a clear indication of the complex formation between them. The visual inspection of observed fluorescence quenching results at λex = 280 nm and 295 nm has shown the substantial involvement of tyrosine residue, even larger than tryptophan. However, after the correction of inner filter effect of the observed data, it became clear that tyrosine has a negligible role in quenching. A 20-fold decrease in quenching constant was found in the corrected data, as compared to the observed data at λex = 280 nm. There was a 11 weak binding between BSA and gemcitabine accompanied by dynamic quenching. The secondary structure of BSA remained almost intact in the presence of gemcitabine. The primary binding site of gemcitabine inside BSA was the drug binding site 2 or DS II, which is located in the subdomain 3 A. MD Simulation results suggested that gemcitabine doesn't affect or deviate the structure of BSA upon interaction throughout 100 ns time period. The dominating intermolecular forces were hydrophobic forces and hydrogen bonding. A small change in the frontier molecular orbitals of gemcitabine was also observed after its binding with BSA.Communicated by Ramaswamy H.

Therefore, finding an alternate energy source is the primary goal to attain sustainable development. Biodiesel is a promising alternate energy source for compression ignition engines. But it has some drawbacks like lower thermal efficiency, higher emission of smoke, NOx, CO and HC. Adding fuel additives with biodiesel-diesel blends is a fruitful method to overcome these problems. In this work, acetone is used as an oxygenated fuel additive in the volumetric proportion of 5%, 10%, and 15% with biodiesel-diesel blend and named as B20A5, B20A10 and B20A15. The performance, combustion, and emission characteristics of single-cylinder, four-stroke, water-cooled vertical diesel engine has been evaluated. The experimental results revealed that B20A15 has resulted in a nominal increase in brake specific fuel consumption by 8%, brake thermal efficiency of 1%, and reduction in CO by 18.4%, smoke opacity by 4.46%, HC by 1.42%, and NOx by 4.36% when compared to diesel at full load condition.A detailed computational study covering density functional theory (DFT), molecular docking, and molecular dynamics (MD) simulations of some spirocyclic compounds interacting with a B-DNA has been performed. DFT calculations were performed using the B3LYP functional with 6-311++G(d,p) basis set and were used to identify the electrophilic and nucleophilic centers in electrostatic forces. NMR results were in agreement with previous experimental data and approved the reliability of the used method and basis set. The in silico screening results showed that spirocyclic compounds fulfill the Lipinski's rule of five and can be developed as potential oral bioavailable drug candidates. Based on molecular docking results, the binding affinities follow the 4c less then 4d less then 4a = 4b  less then  4e less then 4g  less then  4f order and ranged from -8.6 to -9.7 kcal/mol indicating a reasonably favorable interaction between DNA and investigated compounds. The adducts were stabilized by hydrophobic and hydrogen bonding interactions. The MD simulations performed for 100 ns and the results are reported in terms of variables such as root-mean-square deviation (RMSD), root-mean-square fluctuation (RMSF), center of mass (COM) separation distance between DNA and ligands, intermolecular hydrogen bonds, and radial distribution functions (RDF). The MD simulations demonstrated that compounds 4a and 4d bind into the minor groove of 1BNA and may act as potential biological probes for B-DNA.Communicated by Ramaswamy H.

Spectral domain optical coherence tomography (SD-OCT) and OCT angiography (OCT-A) revealed outer retinitis with loss of the ellipsoid layer and choriocapillaris flow voids. link2 Systemic work-up revealed syphilis. Upon systemic treatment with antibiotics, the patients recovered their vision and the OCT and OCT-A abnormalities partially resolved.Conclusions Transient choriocapillaris flow voids characterize ASPPC and may be responsible for the visual loss seen in these patients.Advances in neonatology have led to improved survival for periviable infants. Immaturity still carries a high risk of short- and long-term harms, and uncertainty turns provision of life support into an ethical dilemma. Shared decision-making with parents has gained ground. link3 However, the need to start immediate life support and the ensuing difficulty of withdrawing treatment stands in tension with the possibility of a fair decision-making process. Both the parental "instinct of saving" and "withdrawal resistance" involved can preclude shared decision-making. To help health care personnel and empower parents, we propose a novel approach labeled "postponed withholding." In the absence of a prenatal advance directive, life support is started at birth, followed by planned redirection to palliative care after one week, unless parents, after a thorough counseling process, actively ask for continued life support. Despite the emotional challenges, this approach can facilitate ethically balanced decision-making processes in the gray zone.Aim Low frequency stimulation (LFS) inhibits neuronal hyperexcitability following epileptic activity. However, knowledge about LFS' inhibitory mechanisms is lacking. Here, α1 and α2 adrenergic receptors' roles in mediating LFS inhibitory action on high-K+ induced epileptiform activity (EA) was examined in rat hippocampal slices.Materials and methods LFS (1 Hz, 900 pulses) was applied to the Schaffer collaterals. Whole-cell, patch clamp recording was used to measure changes in CA1 pyramidal neurons' excitability. By applying high-K+ on hippocampal slices, EA was induced, and neuronal excitability increased.Results When administered at the beginning of EA, LFS reduced neuronal excitability. In the presence of prazosin (10 µM, an α1 adrenergic receptor antagonist) and yohimbine (5 µM, an α2 adrenergic receptor antagonist), LFS' typically has a restorative impact on EA-induced membrane potential hyperpolarization and spike firing frequency, but this effect was reduced after high-K+ washout; These antagonists did not have a significant effect on LFS' inhibitory action on spike firing during EA.Conclusion These findings suggest that LFS' anticonvulsant effect, on neuronal hyperexcitability following high-K+ EA, may be mediated partly through α adrenergic receptors in hippocampal slices.
To examine the therapeutic value of lower extremity functional electrical stimulation (FES) - evoked cycling on functional independence, health status, gait parameters, pulmonary functions, and biochemical values in patients with chronic complete/incomplete spinal cord injury (SCI).

Fifteen patients with SCI (duration of more than 6 months) who were able to stand up and walk with long leg braces or assistive devices and had stable neurological status and trunk balance undertook FES cycling for 6 weeks (three times per week). The main outcomes were Functional Independence Measure (FIM), Nottingham Health Profile (NHP), 6-minute walk test (6MWT), and 20-meter walk test (20MWT). Secondary outcomes include measurements of pulmonary function tests and biochemical values. All parameters were evaluated at the beginning and end of the program.

Improvements were seen in motor and total scores of FIM (
 = 0.007), physical mobility subscale of NHP (
 = 0.011), 6MWT (
 = 0.001), and 20MWT (
 = 0.011). In pulmonary functions, only forced vital capacity (FVC) levels demonstrated a significant increase compared with baseline (
