Abstract
This is a case report of a 78-year-old male who underwent a sub-coronary aortic valve and root replacement due to valve dehiscence and aortic root pseudoaneurysm. The patient had complex anomalous coronary anatomy and had undergone a previous tissue aortic valve replacement in 2013. The patient made an uneventful recovery and was discharged from the hospital five days later. The authors suggest that the sub-coronary root replacement technique should be considered in elderly patients and patients with complex coronary anatomy.

Abstract
Background With an increasing number of patients undergoing mitral valve repair, more patients are presenting for reoperation. This study aimed to evaluate factors influencing mortality and survival of patients undergoing reoperation for mitral valve surgery after previous mitral valve repair under a single surgeon. Methods We retrospectively collected data from 117 patients who underwent reoperation after previous mitral valve repair between 2010 and 2022. We aimed to identify preoperative, operative, and postoperative factors affecting outcomes. The primary outcome was overall survival, and the secondary outcomes included prolonged hospital stay and in-hospital mortality. The mean follow-up was 9.13 ± 10.36 years (median, 6.50 years). Results Out of 117 patients, 85 underwent mitral valve replacement (MVR) and 32 underwent mitral valve repair (MVr). The mean age was 64.7 ± 12.7 years (65.5 ± 12.2 years in the MVR group and 62.7 ± 14.0 years in the MVr group), and 66 (56.4%) were men. On a standard multivariate analysis of the overall factors influencing mortality, advanced age was associated with a higher risk of overall mortality (hazard ratio [HR], 1.07; 95% confidence interval [CI], f1.03-1.12; P = .001). The urgency of surgical intervention also played a role, with a higher risk of in-hospital mortality in patients undergoing emergency reoperation (HR, 1.55; 95% CI, 1.60-149.05; P = .02). Furthermore, the presence of mixed lesions, encompassing both mitral regurgitation and stenosis, was strongly linked to increased overall mortality (HR, 17.09; 95% CI, 4.06-71.94; P < .001) and in-hospital mortality (HR, 1.75; 95% CI, 15.83-1925.61; P < .001). Infective endocarditis emerged as a prominent risk factor for overall mortality (HR, 992.08; 95% CI, 85.74-11,479.08; P < .001) and in-hospital mortality (HR, 5.83; 95% CI, 514.81-65,932.99; P < .001). Additionally, chronic obstructive pulmonary disease was associated with a significantly increased risk of overall mortality (HR, 4.3; 95% CI, 1.24-14.97; P = .02). Conclusions Our single surgeon experience demonstrates that mitral valve reoperation after a previous repair is associated with good outcomes and survival.

Abstract
Aberrant origin of coronary artery is a rare congenital anomaly associated with increased risk of myocardial ischemia and sudden death, with the highest risk lesions being those arising from the opposite sinus of Valsalva. We report a case with an aberrant right coronary artery arising superior to the left coronary cusp, with a slit-like ostium, having an inter-arterial and intramural course through the aortic root, that underwent repositioning of the right coronary artery. We believe such cases warrant surgical correction and reimplantation is a safe, effective and reproducible technique.

Abstract
Biofilm formation hinders the activity of antimicrobial drugs at the site of infections and any agent that can act on both Gram-positive and Gram-negative bacteria by inhibiting the bacterial growth and rupturing the biofilm is needed to manage infection. In the present study, we have synthesized zirconia nanoparticles (ZrO2 NPs) and copper doped zirconia nanoparticles (Cu-ZrO2 NPs) and characterized them using dynamic light scattering, X-ray diffractometry, and scanning electron microscopy (SEM). The size of the Cu-ZrO2 NPs drastically reduced compared to ZrO2 NPs, and the antimicrobial activity was studied against Gram-positive bacteria (Lactobacillus sp.) and Gram-negative bacteria (Pseudomonas aeruginosa), respectively. The synthesized Cu-ZrO2 NPs showed superior inhibitory action against Lactobacillus sp. compared to ZrO2 NPs, due to the negatively charged cell wall of Lactobacillus sp., which could attract readily the positively charged Cu-ZrO2 NPs, thereby inhibiting its activity. The biocompatibility was tested using XTT assay in FL cells, and the results demonstrated that Cu-ZrO2 NPs were nontoxic to mammalian cells. Hence, it could be proposed that the synthesized Cu-ZrO2 NPs possess possible biomedical applications and can be used as antibacterial agents without causing toxicity in mammalian cells.

Abstract
BACKGROUND Extra Pulmonary Tuberculosis (EPTB) is a significant health problem in both developing and developed countries. Spinal tuberculosis (STB) is one of the significant forms of EPTB lacking epidemiological data. The present study was conducted to study the clinical, radiological, microbiological and histopathological features, treatment and outcome of Spinal tuberculosis. METHODS This study was conducted for a duration of 19 years, from 2000 to 2018 at the department of Neuromicrobiology, NIMHANS, Bengaluru. It comprised of 252 patients with STB. All patients were diagnosed with the clinical features and confirmed by radiological, microbiological and histopathological findings. RESULTS Results were tabulated and statistically studied. The most common age group is 30-40 years with male preponderance. Most patients presented with motor paraplegia/para paresis (99.6%). Thoracic spine was the most common vertebra affected (47.62%). The commonest imaging feature is soft tissue collection (81.74%). Most common histopathological feature was necrotising granulomatous inflammation (65.87%). Microbiology reports showed growth of Mycobacterium tuberculosis (MTB) in 29.76%, Ziehl Neelsen (ZN) smear showed acid fast bacilli (AFB) in 25.79%. Anti tubercular drugs and surgery were advised in 55.55% patients and only anti TB drugs for 39.28%. The entire course of anti tubercular treatment (ATT) was completed in 60.71% and 4.76% were defaulters. CONCLUSION Spinal tuberculosis is a global disease, timely diagnosis with clinical, imaging, microbiological, histopathological features and complete course of anti-tubercular treatment along with symptomatic treatment appears to be safe and effective.

Abstract
A low power Programmable Analog Front End (PAFE) for biopotential measurements is presented in this paper. The PAFE circuit processes electrocardiogram (ECG), electromyography (EMG) and electroencephalogram (EEG) signals with higher accuracy. It consists mainly of improved transconductance programmable gain instrumentational amplifier (PGIA), programmable high pass filter (PHPF), and second order low pass filter (SLPF). A 15-bit programmable 5-stage successive approximation analog-to-digital converter (SAR-ADC) is implemented for improving the performance, whose power consumption is reduced due to multiple stages and by OTA/Comparator sharing technique between the stages. The power consumption is further reduced by operating the analog portion of PAFE on 0.5V supply voltage and digital portion on 0.3V supply voltage generated internally through a voltage regulator. The proposed low power PAFE has been fabricated in 180nm standard CMOS process. The performance parameters of PAFE in 15-bit mode are found to be, gain of 31-70 dB, input referred noise of 1.15 μVrms, CMRR of 110 dB, PSRR of 104 dB, and signal-to-noise distortion ratio (SNDR) of 83.5dB. The power consumption of the design is 1.1 μW @ 0.5 V supply voltage and it occupies a core silicon area of 1.2 mm2.

Abstract
Background Tetralogy of Fallot and absent pulmonary valve (TOF/APV) is associated with significant pulmonary artery dilatation and airway compression. Methods We performed a retrospective review of 73 consecutive patients who underwent repair for TOF/APV between January 2005–August 2015. Mean age was 6.4 ± 5.6 years (28 days–22 years). The right ventricular outflow tract (RVOT) was reconstructed using varied techniques. Freedom from RVOT gradients and re-operation was studied. Results There were four (5.5%) early deaths, two each in infants and older children. Median ICU stay was 2 days (range, 1–12 days). Mean ICU stay for, infants, children and adults, was 6.5 ± 6.04, 2.75 ± 2.45, and 2.33 ± 1.03 days, respectively (p = 0.0762). Median hospital stay was 6 days (range, 4 to 15 days). Mean hospital stay for, infants and children and adults was 7 ± 2, 6.75 ± 2.39, and 6.33 ± 1.63 days, respectively (p = 0.325). Mean follow up was 65 ± 36.6 months (median 56 months, range 7–126 months). On follow up echocardiography, 14 (21.21%) had no pulmonary regurgitation. 21 (31.81%) had mild PR patients, 8 (12.12%) moderate PR and 19 (28.78%) had severe PR. There were five (7.5%) reoperations. Five and ten-year survival was 95% ± 2.12 and 92.3% ± 3.45 respectively. Freedom from RVOT reoperation was 93 ± 2.62% and 89 ± 3.87% at 5 and 10 years. Conclusions In contrast to children and adults with TOF/APV, infants carry significant early mortality. But the mid-term outcome for patients who survive the initial repair of TOF/APV is acceptable. However, these patients require constant surveillance and irrespective of the methods of RVOT management, the reoperation rates are expected to be high as more of these patients survive into adulthood.

Abstract
This study investigates the structural and optical properties in the cribellate silk of the sheet web spider Stegodyphus sarasinorum Karsch (Eresidae) and the combined dragline, viscid silk of the orb-web spiders Argiope pulchella Thorell (Araneidae) and Nephila pilipes Fabricius (Nephilidae). X-ray diffraction (XRD), Fourier transform infra-red (FTIR), Ultraviolet-visible (UV-Vis) and fluorescence spectroscopic techniques were used to study these three spider silk species. X-ray diffraction data are consistent with the amorphous polymer network which is arising from the interaction of larger side chain amino acid contributions due to the poly-glycine rich sequences known to be present in the proteins of cribellate silk. The same amorphous polymer networks have been determined from the combined dragline and viscid silk of orb-web spiders. From FTIR spectra the results demonstrate that, cribellate silk of Stegodyphus sarasinorum, combined dragline viscid silk of Argiope pulchella and Nephila pilipes spider silks are showing protein peaks in the amide I, II and III regions. Further they proved that the functional groups present in the protein moieties are attributed to α-helical and side chain amino acid contributions. The optical properties of the obtained spider silks such as extinction coefficients, refractive index, real and imaginary dielectric constants and optical conductance were studied extensively from UV-Vis analysis. The important fluorescent amino acid tyrosine is present in the protein folding was investigated by using fluorescence spectroscopy. This research would explore the protein moieties present in the spider silks which were found to be associated with α-helix and side chain amino acid contributions than with β-sheet secondary structure and also the optical relationship between the three different spider silks are investigated. Successful spectroscopic knowledge of the internal protein structure and optical properties of the spider silks could permit industrial production of silk-based fibres with unique properties under benign conditions.

Abstract
Tuberculosis of the female reproductive tract affects usually reproductive age group and is a common cause of infertility with tubal pathology. Diagnosis of the female genital tract tuberculosis is challenging and, very often missed due to the unusual presentations and lack of specific diagnostic tests. This may occasionally lead to unnecessary surgical procedures. We present two case reports of female genital tuberculosis (FGTB) who presented to us with symptoms mimicking malignancy diagnosed TB only on histopalthology.

Abstract
BACKGROUND This study was undertaken to evaluate the role of day 3 FSH/LH ratio and day 3 LH level as predictors of IVF cycle outcomes. METHODS This prospective observational study was undertaken in the IVF and Reproductive Biology Centre and Lok Nayak Hospital, affiliated to Maulana Azad Medical College, in New Delhi, India. The study included 105 women who underwent controlled ovarian hyperstimulation for in vitro fertilization. Characteristics of IVF cycles and outcomes were studied in patient subgroups based on day 3 FSH/LH ratio (<2 and ≥2) and day 3 LH levels (>3 and ≤3 mIU/ml). The student t-test, Bartlett's test, chi-squred (χ(2) ) and Fisher's exact test, and linear regression model were used for data analysis. A p-value less than 0.05 was considered as statistically significant. RESULTS Women with an elevated FSH/LH ratio ≥2 (n = 31) required higher doses of gonadotrophins (3019.34 vs. 2482.43 IU). The outcome of IVF was poor in these patients and they had fewer number of mature follicles (>16 mm) (5.44 vs. 6.09), less E2/mature follicle ratio (4.65 vs. 6.36), fewer retrieved oocytes (6.67 vs. 9.09) and fewer pregnancy rates (11.1% vs. 33.8%). On the other hand, patients with low basal LH levels (≤3 mIU/ml) did not differ significantly in terms of response to controlled ovarian hyperstimulation except for fewer number of retrieved oocytes (7.33 vs. 7.91) but there was a trend towards poor pregnancy rates (7.33 vs. 7.91) but there was a trend towards poor pregnancy rates as compared to subgroup with LH levels >3 mIU/ml. CONCLUSION Elevated day 3 FSH/LH ratio is associated with inferior outcome in IVF treatment cycles and it could be used as an additional predictor of decreased ovarian reserve.

Abstract
OBJECTIVE Inflammatory processes play a role in the pathogenesis of atherosclerosis, and plasma circulatory markers have been associated with cardiovascular risk. There is no single report in which adhesion molecule and circulatory cytokines have been evaluated in a single population set with coronary artery disease (CAD) on the basis of gender. Thus, we evaluated plasma circulatory markers in patients with CAD and in controls that were divided by gender (because functioning of circulatory markers and response toward conventional factors are not identical in men and women) and by conventional risk factors such as smoking and alcohol intake. METHODS A total of 192 patients with CAD (148 male and 44 female) and 192 controls with no symptoms of CAD (142 male and 50 female) were enrolled. Detection of concentration to high-sensitivity C-reactive protein (hsCRP), interleukin (IL)-2, IL-4, IL-6, IL-8, IL-10, IL-13, interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha, and adhesion molecules (intercellular adhesion molecule [ICAM]-1 and vascular adhesion molecule [VCAM]-1) was performed using enzyme-linked immunosorbent assay kits. RESULTS In male patients with CAD, levels of IL-4, IL-6, IL-8, IL-13, ICAM-1, VCAM-1, hsCRP (P < .001), and IFN-gamma (P = .003) were significantly higher compared with controls; however, levels of IL-10 were significantly lower (P < .001). In female patients with CAD, levels of IL-4, hsCRP, VCAM-1 (P = .001), and IL-13 (P = .028) were significantly higher and IL-10 levels were significantly lower (P < .001) compared with controls. In addition, levels of circulatory markers were strongly associated with male smokers and imperceptibly associated with male alcoholics and female smokers and alcoholics. CONCLUSION This study compared the plasma circulatory markers between patients with CAD and healthy controls, between patients with CAD who smoke and controls, and between alcoholic patients with CAD and controls divided by gender. Moreover, among circulatory markers studied, higher levels were found for IL-4, IL-13, hsCRP, and VCAM-1, and lower levels were found for IL-10 in male and female patients with CAD compared with healthy controls.

Abstract
Coronary artery disease (CAD) is a public health problem accounting for an estimated one-third of deaths overall. A potential link between infectious agents and atherosclerosis has been suggested. Data obtained from several seroepidemiological studies have suggested that infection with Chlamydophila pneumoniae, Helicobacter pylori, cytomegalovirus and herpes simplex virus-1 can initiate or maintain the atherosclerotic process. However, there is no single study in which multiple infectious agents have been detected together in different vascular locations in the same population. This would help in determining if there is any leading pathogen in atheromatous plaques of CAD patients. Hence, we screened for C. pneumoniae, H. pylori, CMV and HSV-1 in different vascular locations of CAD patients using quantitative real-time (RT) PCR. We performed multiplex RT-PCR for detecting pathogens, viz. C. pneumoniae, H. pylori, CMV and HSV-1 in different vascular locations of CAD patients. Percent positivity scores for C. pneumoniae, H. pylori, CMV and HSV-1 in different vascular locations were as follows: aorta (64.7, 35.3, 11.7 and 11.7 respectively); carotid (27.2, 27.2, 9 and 0 respectively); coronary artery (58.3, 33.3, 16.6 and 8.3 respectively). Combined positivity for C. pneumoniae (C. pneumoniae IgA and RT-PCR for C. pneumoniae) was the highest compared with all other groups. Aorta and coronary artery were more susceptible to these pathogens as compared with carotid artery. Moreover, CAD patients' characteristics were associated with C. pneumoniae positivity (C. pneumoniae IgA and RT-PCR), suggesting thereby that C. pneumoniae may have caused chronic persistent infection in CAD.
