Abstract
Chronological sequencing of ink strokes has been a challenge for the Forensic Document Examiners (FDE). Document forgery is a common practice and the ability to determine the order in which the primary and the subsequent strokes have been made is crucial for establishing the authenticity of a document. Lately, the prime thrust of establishing the sequence of intersection of ink lines has shifted from an optical to an analytical approach. Several studies have been reported to explore the use of spectroscopic techniques in determining the sequence of ink strokes made using gel pen inks, ball pen inks, fountain inks, printed ink, stamp inks, etc. The present study aims to study the existing trends in examining the sequence of ink strokes or crossing of lines using vibrational spectroscopic techniques viz. Infrared and Raman Spectroscopy. Several interesting inferences have been drawn, such as factors like paper type and time gap between the application of two intersecting strokes does not influence the determination of the sequence of inter-crossing strokes. A trend of using two analytical techniques viz. VSC, AFM, HPTLC, TOF-SIMS, and SEM/EDX with vibrational spectroscopic techniques have been found to provide reliable results. The study also suggests future research directions in the field, aiming to address challenges faced by the FDEs and provide accurate and reliable solutions for document examination.

Abstract
Counterfeiting or forged imitation of banknotes is a perpetual practice engulfing global economies. This not only poses challenges for the material scientists to come forth with advanced security materials but also demands veracious forensic examination to detect counterfeits. The present article pursues novel efforts in summarizing a study that lays focus on the recent optical and analytical examinations being used for the characterization and detection of chemical profiles of authentic and counterfeited banknotes. The article briefs the trends in banknote materials, security paper manufacturing process, security inks used for printing, and types of the security printing process in banknote practices. Reported literature shows the introduction of new anti-counterfeiting materials viz. magnetically-responsive photonic anti-counterfeiting watermarks, and fluorescent nanoparticles that can be used as anti-counterfeiting inks, anti-stokes inks, metameric inks, etc. Analytical techniques such as IR spectroscopy, Raman spectroscopy, Mossbauer spectroscopy, X-ray diffraction, X-ray fluorescence, LIBS, XRF, ELDI-MS, EASI/DESI-MS, HPLC, VSC, AFM, etc. in conjunction with different chemometrics approaches have been critically discussed. The study also presents the future scope in banknote examination like the use of hyper spectral imaging and sensor-based counterfeit detection systems.

Abstract
Thermal papers are replacing the conventional form of printing and are being extensively used across the globe. This study encompasses a non-destructive approach to examine thermal papers by using ATR-FTIR spectroscopy and Video Spectral Comparator (VSC), where the former technique helps in characterizing and discriminating different samples and the latter helps in deciphering the faded prints on thermal paper. The qualitative analysis of the spectroscopic data based on peak to peak comparison and quantitative analysis using chemometrics has been done to obtain high discriminating power. Multivariate analysis using HCA gave a discriminating power of 83.82% and PCA showed a variance of 95.64%. The strength of the study is portrayed through the decipherment of artificially and naturally faded thermal papers using VSC and analyzing the effect of different storing conditions on their rate of fading.

Abstract
OBJECTIVES Children accessing healthcare systems represent a vulnerable population with risk factors for poor health outcomes, including vaccine-preventable diseases. We aimed to quantify missed vaccination opportunities among hospitalised children in India, and identify vaccination barriers perceived by caregivers and healthcare providers. DESIGN Cross-sectional study. SETTING Two public-sector tertiary-care hospitals in northern India, during November 2018 and March 2019. PARTICIPANTS We tracked 263 hospitalised children aged 1-59 months through hospital discharge, to assess vaccination status, and document catch-up vaccinations given during the hospital stay. We interviewed caregivers and healthcare providers to assess their perceptions on vaccination. OUTCOMES Proportion of hospitalised children considered under-vaccinated for their age; proportion of missed opportunities for vaccination among under-vaccinated children who were eligible for vaccination; and vaccine coverage by antigen. RESULTS We found that 65.4% (172/263) of hospitalised children were under-vaccinated for their age when they presented to the hospital. Among under-vaccinated children, 61.0% were less than 4 months old, and 55.6% reported prior contact with a health facility for a sick visit. The proportion of under-vaccinated children in hospitals were higher compared with the general population as indicated by regional vaccination coverage data. Among under-vaccinated children who were tracked till discharge, 98.1% (158/161) remained incompletely vaccinated at discharge and were considered 'missed opportunities for vaccination'. Perceived vaccination contraindications that are not part of established contraindications included in national and international guidelines was the most common reason for healthcare providers not to vaccinate children during hospital stay. Among caregivers of under-vaccinated children, 90.1% reported being comfortable having their children vaccinated while they were sick, if recommended by the healthcare provider. CONCLUSION This pilot study confirmed that hospitalised sick children had substantial missed vaccination opportunities. Addressing these opportunities through concerted actions involving caregivers, healthcare providers and healthcare systems can improve overall vaccination coverage.

Abstract
Human papillomavirus (HPV) is a common sexually transmitted infection. Binge drinkers often engage in HIV/HPV co-infection high-risk behaviors. We examined the association between binge drinking, HIV/HPV co-infection risk, HIV testing and HPV vaccination among young adults. Data from the 2017 Behavioral Risk Factor Surveillance System survey were examined. Participants (N = 430/450,016; 0.11%) were HPV vaccine-eligible young adults ages 18-26 years. Multivariable logistic regression examined the association between binge drinking in the past 30 days, HIV/HPV co-infection high-risk risk behaviors, HIV testing, and HPV vaccination (initiated/completed, unvaccinated) among young adults. Respondents were primarily cisgender (99.8%), non-Hispanic White (41.4%), employed (46.2%) or student (35.4%), and insured (68.2%). Most did not binge drink (55.2%). The majority did not engage in HIV/HPV co-infection high-risk risk behaviors (78.2%). More than one-half had never been tested for HIV (59%) nor vaccinated against HPV (60.6%). Although binge drinkers (44.8%) were significantly more likely to engage in HIV/HPV co-infection high-risk behaviors (OR = 2.1; 95% CI: 1.0-4.5), binge drinking was not positively associated with HIV testing (OR = 0.98; 95% CI: 0.63-1.53). After adjusting for demographics and HIV/HPV co-infection high-risk behaviors, one (aOR = 2.71; 95% CI: 1.11-6.65) and two episodes (aOR = 3.05; 95% CI: 1.26-7.41) of binge drinking in the past 30 days were significantly associated with HPV vaccination uptake. Positive associations between HPV vaccination and participants having an HIV test in 2017 (aOR = 3.86; 95% CI: 1.42-10.55) and before 2017 (aOR = 2.62; 95% CI: 1.23-5.56) were also statistically significant. Because young adult binge drinkers are more likely to engage in HIV/HPV co-infection high-risk behaviors, promoting HPV vaccination and HIV testing are important public health objectives.

Abstract
INTRODUCTION In India, glaucoma is the third most common cause of blindness, reflecting both its asymptomatic presentation and a lack of knowledge in the general population. No previous published data of glaucoma awareness among the Indian Armed forces personnel exists, who constitute a unique group consisting of people drawn from all parts of the country and society. METHODS Bilingual questionnaires were distributed to 496 serving Army, Navy and Air Force personnel serving in units local to the Zonal military hospital in North India. Having heard of the term glaucoma resulted in the subject being 'glaucoma aware', while 'knowledge of glaucoma' required at least three out of six questions to be answered correctly. RESULTS 110/496 (22%) participants were found to be glaucoma aware, while knowledge of glaucoma was found in 60/496 (12%) participants. CONCLUSIONS This study demonstrates that glaucoma awareness and knowledge is high compared with rural or urban Indian populations. This is likely reflects the frequent health camps conducted by the armed forces and periodic medical examinations. However, these figures are still low compared with developed countries and likely reflects differences in education standards, socioeconomic status and differing influences of the media.

Abstract
Abstract
Double heterozygosity is an extremely rare occurrence in hereditary breast and ovarian cancer syndrome (HBOC [MIM 604370; MIM 612555]) where two pathogenic variants, one in BRCA1 and one in BRCA2, are found in an individual. To date, only a few case reports and case series have been reported in the literature (1-3). Furthermore, little is known about the clinical characteristics, family history, and tumor histology in these patients. In this study, we utilized targeted gene testing with next-generation sequencing (NGS) technology in an early-onset metastatic breast cancer patient from France. We evaluated germline variants using Pathway Genomics' BRCATrueTM NGS test, which analyzes variants covering all exons and exon flanking regions in both the BRCA1 and BRCA2 genes. All variant calls were determined after alignment and mapping to the GRCh37/hg19 reference genome. Variant calls were confirmed by Sanger sequencing. In this patient, a c.1016dupA (p.V340GfsX6) frameshift variant was found in BRCA1 along with a c.6814delA (p.R2272EfsX8) frameshift variant in BRCA2. Both frameshift variants are predicted to truncate the BRCA proteins. The BRCA1 c.1016dupA variant is considered a Norwegian founder mutation but has also been observed in individuals who are of French-Canadian, French, Italian or Dutch ancestry (4-7). The BRCA2 c.6814delA (p.R2272Efs*8) pathogenic variant, also known as 7042delA, is predicted to truncate the BRCA2 protein and has been identified in individuals with a personal or family history of breast and/or ovarian cancer (8,9). To the best of our knowledge, the combination of these two pathogenic variants in an individual has not been previously reported. In a clinical diagnostic setting, the possibility of double heterozygosity of pathogenic variants in more than one susceptibility gene should be considered, especially in patients with early-onset metastatic cancers. Furthermore, genetic testing and genetic counseling should also be indicated for high-risk family members.

Abstract
We compared pyruvate accumulation in six strains of Escherichia coli and their corresponding ppc mutants. Each strain contained a mutation of a gene involved in the pathway to acetate synthesis. Strains with mutations in genes encoding the pyruvate dehydrogenase complex generally exhibited the greatest pyruvate accumulation of which CGSC6162 (an aceF mutant) and CGSC6162 Delta ppc were studied in greater detail in controlled fermenters. Both CGSC6162 and CGSC6162 Delta ppc accumulated greater than 35 g/l pyruvate in a medium supplemented with acetate. We observed pyruvate mass yields from glucose of 0.72 in CGSC6162, with volumetric productivities above 1.5 g l(-1) h(-1). For CGSC6162 Delta ppc, we observed pyruvate yields of 0.78 and volumetric productivities above 1.2 g l(-1) h(-1). CGSC6162 consumed all initially supplied acetate, while CGSC6162 Delta ppc first consumed and then generated acetate during the course of a 36 h fermentation. Acetate generation and pyruvate oxidase activity was pH- and temperature-dependent, with a pH of 7.0 and the lowest temperature studied (32 degrees C) favoring the greatest pyruvate generation. Lactate was an unexpected by-product even though measured lactate dehydrogenase (LDH) activity was very low.

Abstract
Migraine is considered to be a functional neurological disorder. For several years cerebral blood flow studies have been fueling the controversy surrounding the pathophysiology of migraine headache. Tc-99m HMPAO SPECT brain imaging was performed during the headache-free period in 44 migraineurs. The findings were compared with those of age 17 and sex-matched controls. The SPECT analysis was performed by using a 360 degrees rotating single head gamma camera system (Toshiba GCA 602A/SA, Japan), equipped with a LEAP collimator, interfaced to a Toshiba computer system, after 20 minutes following the injection of 350-550 MBq of Tc-99m HMPAO. The SPECT images revealed clear interhemispheric asymmetry in the upper frontal and occipital parts of the brain in migraineurs. It is suggested that an impaired regional cerebral vascular autoregulation may exist even during headache-free intervals in patients suffering from migraine.

Abstract
Culture supernatants containing interleukin-2-like activities (CS-IL2) were prepared from goat peripheral blood cells (mononuclear cells 75% and polymorphonuclear cells 25%). These were stimulated with three costimulants, (tetradecanoyl phorbol acetate, indomethacin and calcium ionophore A23187), either alone or in different combinations, in RPMI-1640 medium (containing 0.5% bovine serum albumin (BSA)) with or without serum. After 18 h of incubation with costimulants, concanavalin A (Con A) was added and the incubation was continued for next 48 h. Higher interleukin-2 (IL-2)-like activities were generated in the culture supernatants prepared in RPMI-1640 growth medium containing 0.5% BSA without serum. Further, IL-2-like activities were much higher in culture supernatants obtained by stimulation with all the three costimulants, as well as Con A, than the two costimulants with Con A or any of the costimulants with Con A.
