Inorganic nitrite alters mitochondrial dynamics without overt changes in cell death and mitochondrial respiration in cardiomyoblasts under hyperglycemia. Toxicol In Vitro 2020; 70:105048.

Abstract
Inorganic nitrate or nitrite supplementation has been reported to demonstrate positive outcomes in rodent models of obesity and diabetes as well as in type 2 diabetic humans and even included in clinical trials pertaining to cardiovascular diseases in the recent decade. However, there are contrasting data regarding the useful and toxic effects of the anions. The primary scope of this study was to analyze the beneficial/detrimental alterations in redox status, mitochondrial dynamics and function, and cellular fitness in cardiomyoblasts inflicted by nitrite under hyperglycemic conditions compared with normoglycemia. Nitrite supplementation in H9c2 myoblasts under high glucose diminishes the Bcl-xL expression and mitochondrial ROS levels without significant initiation of cell death or decline in total ROS levels. Concomitantly, there are tendencies towards lowering of mitochondrial membrane potential, but without noteworthy changes in mitochondrial biogenesis and respiration. The study also revealed that under high glucose stress, nitrite may alter mitochondrial dynamics by Drp1 activation possibly via Akt1-Pim1 axis. Moreover, the study revealed differential effects of Drp1 silencing and/or nitrite under the above glycemic conditions. Overall, the study warrants more research regarding the effects of nitrite therapy in cardiac cells exposed to hyperglycemia.

Abstract
Staphylococcus aureus is not only part of normal flora but also an opportunistic pathogen relevant to microbial genomics, public health, and veterinary medicine. In addition to being a well-known human pathogen, S. aureus causes various infections in economically important livestock animals such as cows, sheep, goats, and pigs. There are very few studies that have examined the pan-genome of S. aureus or the host-specific strains' pan-genomes. We report on livestock-associated S. aureus' (LA-SA) pan-genome and suggest that virulence is not the primary interest in evolution of its genome. LA-SA' complete genomes were retrieved from the NCBI and pan-genome was constructed by high-speed Roary pipeline. The pan-genome size was 4637 clusters, whereas 42.46% of the pan-genome was associated with the core genome. We found 1268 genes were associated with the strain-unique genome, and the remaining 1432 cluster with the accessory genome. COG (clusters of orthologous group of proteins) analysis of the core genes revealed 34% of clusters related to metabolism responsible for amino acid and inorganic ion transport (COG categories E and P), followed by carbohydrate metabolism (category G). Virulent gene analysis revealed the core genes responsible for antiphagocytosis and iron uptake. The fluidity of pan-genome was calculated as 0.082 ± 0.025. Importantly, the positive selection analysis suggested a slower rate of evolution among the LA-SA genomes. We call for comparative microbial and pan-genome research between human and LA-SA that can help further understand the evolution of virulence and thus inform future microbial diagnostics and drug discovery.

Abstract
AIM The study aimed to assess the nature of animal origin Staphylococcus aureus strains. The study has zoonotic importance and aimed to compare virulence between two different hosts, i.e., bovine and ovine origin. MATERIALS AND METHODS Conventional polymerase chain reaction-based methods used for the characterization of S. aureus strains and chick embryo model employed for the assessment of virulence capacity of strains. All statistical tests carried on R program, version 3.0.4. RESULTS After initial screening and molecular characterization of the prevalence of S. aureus found to be 42.62% in bovine origin samples and 28.35% among ovine origin samples. Meanwhile, the methicillin-resistant S. aureus prevalence is found to be meager in both the hosts. Among the samples, only 6.8% isolates tested positive for methicillin resistance. The biofilm formation quantified and the variation compared among the host. A Welch two-sample t-test found to be statistically significant, t=2.3179, df=28.103, and p=0.02795. Chicken embryo model found effective to test the pathogenicity of the strains. CONCLUSION The study helped to conclude healthy bovines can act as S. aureus reservoirs. Bovine origin S. aureus strains are more virulent than ovine origin strains. Bovine origin strains have high probability to become zoonotic pathogen. Further, gene knock out studies may be conducted to conclude zoonocity of the bovine origin strains.

Abstract
AIMS AND OBJECTIVES The aim is to study the effectiveness of 2 mm three-dimensional (3D) titanium miniplates and 2 mm conventional titanium miniplates in osteosynthesis of mandibular fractures by comparing the change in bite force. METHODOLOGY The study comprised forty patients of age group 20-40 years, weighing 55-75 kg having mandibular fractures. Patients were randomly divided into two equal groups In Group A, twenty patients underwent osteosynthesis using 3D titanium miniplates (2.0 mm system), whereas in Group B, twenty patients underwent osteosynthesis using conventional titanium miniplates (2.0 mm system). After fixation of fracture segments with miniplates, the patients were assessed on the basis of evaluation of bite force at incisor, right molar and left molar region after 1, 3, 6 , and 8 weeks. Comparison of change in bite force was done between Group A and Group B at different follow-ups at incisor, right molar, and left molar. RESULTS Bite force recordings showed increasing values at subsequent follow-ups, corresponding to the healing of the fracture in both groups. At follow-up III (6 weeks) and IV (8 weeks), bite force values reached near to those in healthy individuals. A significant difference was observed in change in bite force of Group A and Group B at incisor left molar and right molar on subsequent followups. 3D titanium miniplate requires less surgical exposure of the underlying fracture site, with a minimal traction of the surrounding soft tissue. INTERPRETATION AND CONCLUSION 3D miniplates in mandibular fractures are efficacious enough to bear masticatory loads during the osteosynthesis of fractures. It gives the advantage of greater stability, increased bite force, reduced implant material, and 3D stability.

Abstract
A 5-year-old boy was diagnosed to have supravalvular aortic stenosis (SVAS). On evaluation of CT angiogram, there was associated bovine aortic arch (BAA). Association of BAA with SVAS has not been previously reported in literature, and to best of our knowledge, this is the first case report of SVAS with BAA. Recent studies show BAA as a marker for aortopathy. SVAS is also an arteriopathy. In light of this, SVAS can also possibly be a manifestation of aortopathy associated with BAA.

Abstract
Double outlet right ventricle (DORV) is almost always associated with a ventricular septal defect. The variant of DORV with intact ventricular septum is very uncommon and may be associated with fetal demise or death immediately after birth. Reports of successful palliation of these patients to the stage of superior cavopulmonary anastomosis (bidirectional Glenn shunt) are rare. We describe the case of a child with DORV with intact ventricular septum who underwent successful palliation. This condition often provides a diagnostic, interventional, and surgical challenge. Patients generally require either balloon atrial septostomy or surgical atrial septectomy for survival, with the addition of a Blalock-Tausig shunt or pulmonary artery band depending on the pulmonary blood flow. Very few patients survive to a Glenn procedure. For those who do survive, a decision must be made regarding the management of the hypertensive and hypoplastic left ventricle (LV) and associated mitral regurgitation. The LV can be excluded by either mitral valve avulsion or closure (exclusion) of the mitral valve with a patch. The choice of the technique should be carefully made and depends in part on the size of the LV. In our patient, who was successfully palliated by bidirectional Glenn shunt, the LV was managed by means of mitral valve avulsion.

Abstract
Mononuclear and binuclear copper(II) complexes of 2-benzoylpyridine-N(4)-methyl thiosemicarbazone (HL) were prepared and characterized by a variety of spectroscopic techniques. Structural evidence for the novel sulfur bridged copper(II) iodo binuclear complex is obtained by single crystal X-ray diffraction analysis. The complex [Cu2L2I2], a non-centrosymmetric box dimer, crystallizes in monoclinic C2/c space group and it was found to have distorted square pyramidal geometry (Addison parameter, τ=0.238) with the square basal plane occupied by the thiosemicarbazone moiety and iodine atom whereas the sulfur atom from the other coordinated thiosemicarbazone moiety occupies the apical position. This is the first crystallographically studied system having non-centrosymmetrical entities bridged via thiolate S atoms with Cu(II)I bond. The tridentate thiosemicarbazone coordinates in mono deprotonated thionic tautomeric form in all complexes except in sulfato complex, [Cu(HL)(SO4)]·H2O (1) where it binds to the metal centre in neutral form. The magnetic moment values and the EPR spectral studies reflect the binuclearity of some of the complexes. The spin Hamiltonian and bonding parameters are calculated based on EPR studies. In all the complexes g||>g⊥>2.0023 and the g values in frozen DMF are consistent with the d(x2-y2) ground state. The thermal stabilities of some of the complexes were also determined.

Abstract
Epithelialization of chronic cutaneous wound is troublesome and may require use of skin/cell substitutes. Adipose-derived mesenchymal stem cells (ADMSCs) have immense potential as autologous cell source for treating wounds; they can cross the germ layer boundary of differentiation and regenerate skin. When multipotent adult stem cells are considered for skin regeneration, lineage committed keratinocytes may be beneficial to prevent undesirable post-transplantation outcome. This study hypothesized that ADMSCs may be directed to epidermal lineage in vitro on a specifically designed biomimetic and biodegradable niche. Cells were seeded on the test niche constituted with fibrin, fibronectin, gelatin, hyaluronic acid, laminin V, platelet growth factor, and epidermal growth factor in the presence of cell-specific differentiation medium (DM). The ADMSCs grown on bare tissue culture polystyrene surface in DM is designated DM-control and those grown in basal medium (BM) is the BM-control. Lineage commitment was monitored with keratinocyte-specific markers such as cytokeratin 14, cytokeratin 5, cytokeratin 19, and integrin α6 at the transcriptional/translational level. The in vitro designed biomimetic fibrin composite matrix may have potential application as cell transplantation vehicle.

Gold surface supported spherical liposome-gold nano-particle nano-composite for label free DNA sensing. Biosens Bioelectron 2012; 41:802-8. [PMID: 23141707 DOI: 10.1016/j.bios.2012.10.017] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2012] [Revised: 09/26/2012] [Accepted: 10/04/2012] [Indexed: 10/27/2022]
Abstract
Immobilization of 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE) liposome-gold nano-particle (DOPE-AuNP) nano-composite covalently on 3-mercaptopropionic acid (MPA) on gold surface is demonstrated for the first time for electrochemical label free DNA sensing. Spherical nature of the DOPE on the MPA monolayer is confirmed by the appearance of sigmoidal voltammetric profile, characteristic behavior of linear diffusion, for the MPA-DOPE in presence of [Fe(CN)(6)](3-/4-) and [Ru(NH(3))(6)](3+) redox probes. The DOPE liposome vesicle fusion is prevented by electroless deposition of AuNP on the hydrophilic amine head groups of the DOPE. Immobilization of single stranded DNA (ssDNA) is made via simple gold-thiol linkage for DNA hybridization sensing in the presence of [Fe(CN)(6)](3-/4-). The sensor discriminates the hybridized (complementary target hybridized), un-hybridized (non-complementary target hybridized) and single base mismatch target hybridized surfaces sensitively and selectively without signal amplification. The lowest target DNA concentration detected is 0.1×10(-12)M. Cyclic voltammetry (CV), electrochemical impedance (EIS), differential pulse voltammetry (DPV) and quartz crystal microbalance (QCM) techniques are used for DNA sensing on DOPE-AuNP nano-composite. Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FTIR), Atomic Force Microscopy (AFM), Dynamic Light Scattering (DLS) and Ultraviolet-Visible (UV) spectroscopic techniques are used to understand the interactions between the DOPE, AuNP and ssDNA. The results indicate the presence of an intact and well defined spherical DOPE-AuNP nano-composite on the gold surface. The method could be applied for fabrication of the surface based liposome-AuNP-DNA composite for cell transfection studies at reduced reagents and costs.

Abstract
The objective of the study was to collect repeated, low-stress blood samples from the ulnar vein of chickens required for pharmacokinetic studies or hormonal assays. The study used 5 apparently healthy, unsexed, commercial broiler chickens about 6 weeks old and weighing 1.7-1.9 kg for serial sampling of blood. The study prepared the birds prior to cannulation and penetrated the catheter through the skin and into the lumen of the ulnar vein. The study successfully carried out serial blood samplings in 4 of 5 cannulated birds. Heparin (10%) solution maintained patency and prevented blood clot formation inside the cannula. However, the study found repeated clotting occurring in 1 bird. Cannula failed to maintain patency; the study could not carry out blood sampling properly, which was attributed to air embolism that might have occurred during catheter manipulation or repeated filling of cannula with heparin solution. The study observed no hematoma or inflammation at the site of cannulation. Owing to the advantages and to facilitate compliance with nonhuman animal welfare, this technique seems simple and efficient, allowing adoption for serial blood collection in chickens.

(Z)-N,N-Dimethyl-2-[phen-yl(pyridin-2-yl)methyl-idene]hydrazinecarbothio-amide. Acta Crystallogr Sect E Struct Rep Online 2011; 67:o3195.

Abstract
The title compound, C15H16N4S, exists in the Z conformation with the thionyl S atom lying cis to the azomethine N atom. The shortening of the N—N distance [1.3697 (17) Å] is due to extensive delocalization with the pyridine ring. The hydrazine–carbothioamide unit is almost planar, with a maximum deviation of 0.013 (2) Å for the amide N atom. The stability of this conformation is favoured by the formation of an intramolecular N—H⋯N hydrogen bond. The packing of the molecules involves no classical intermolecular hydrogen-bonding interactions; however, a C—H⋯π interaction occurs.

Abstract
The present study was designed to evaluate the effect of acetaminophen on kidneys of birds by comparison with diclofenac that is used as positive control. The birds of Group I served as negative control and received normal saline, whereas Group II birds received diclofenac injection (2.5 mg/kg IM) and Group III birds received acetaminophen injection (10 mg/kg IM) for a period of seven days daily. The birds treated with diclofenac showed severe clinical signs of toxicity accompanied with high mortality and significant increase (P<0.001) in serum creatinine and uric acid concentration. The creatinine and uric acid concentrations were consistent with gross and histopathological findings. The negative control and acetaminophen-treated groups showed no adverse clinical signs, serum creatinine and uric acid concentrations were normal, and no gross or histopathological changes in kidneys were observed. Thus, it was concluded that acetaminophen can be used for treatment in birds without any adverse effect on kidneys.

Abstract
Acute dermal toxicity study was conducted in rats. The parameters studied were body weight, serum biochemistry and gross pathology. The animals were also observed for clinical signs and mortality after the application of test film. The dermal irritation potential of silk protein film was examined using Draize test. In the initial test, three test patches were applied sequentially for 3 min, 1 and 4 hours, respectively, and skin reaction was graded. The irritant or negative response was confirmed using two additional animals, each with one patch, for an exposure period of 4 hours. The responses were scored at 1, 24, 48 and 72 hours after the patch removal. Skin sensitization study was conducted according to Buehler test in guinea pigs, in which on day 0, 7 and 14, the animals were exposed to test material for 6 hours (Induction phase) and on day 28, the animals were exposed for a period of 24 hours (Challenge phase). The skin was observed and recorded at 24 and 48 hours after the patch removal. In acute dermal toxicity study, the rats dermally treated with silk film did not show any abnormal clinical signs and the body weight, biochemical parameters and gross pathological observations were not significantly different from the control group. In acute dermal irritation study, the treated rabbits showed no signs of erythema, edema and eschar, and the scoring was given as “0” for all time points of observations according to Draize scoring system. In skin sensitization study, there were no skin reactions 24 and 48 hours after the removal of challenge patch, which was scored “0” based on Magnusson/Kligman grading scale.
