    Abstract Background: The WHO 2017 classification of endocrine tumors incorporates lineage-specific transcription factors (TF) and hormone expression for the classification of pituitary adenoma (PA). There is paucity of reports describing the spectrum of PA based on this classification.
    Objective: The aim of this study was to delineate the spectrum of PA based on WHO 2017 classification of endocrine tumors.
    Materials and methods: PA diagnosed in the year 2018 were studied. H and E and hormonal immunohistochemistry (IHC) for GH, PRL, ACTH, TSH, FSH, LH, CK, T-Pit and MIB-1 were performed and the results were analyzed.
    Results: The cohort included 88 cases. M: F ratio was 2:1. Clinically, 22 (25%) were functional and 66 (75%) were non-functional adenomas. Amongst the clinically functional adenomas, GH secreting adenomas were the commonest (68%). Majority (83%) of non-functional adenomas were hormone positive with gonadotroph adenomas being the commonest (72.7%). Eleven (12.5%) PA were clinically and hormonally silent. Three of these showed intense nuclear T-Pit positivity, classifying them under silent corticotroph adenoma. Lineage of the remaining eight adenomas remained undetermined, since, IHC for Pit-1 and SF-1 was not performed. The aggressive adenomas identified by IHC included sparsely granulated somatotroph adenoma, Crooke cell adenoma, silent corticotroph adenoma, densely granulated lactotroph adenoma in men and constituted 17% of the PA. Four (4/88) cases were clinically invasive.
    Conclusion: A large majority of PA including aggressive adenomas can be identified by IHC. Addition of T-Pit helped to identify silent corticotroph adenoma. Pit -1 and SF-1 TF would help identify plurihormonal Pit-1 PA and null cell adenomas.

    Abstract Background: Cancer is, at present, among the leading causes of morbidity globally. Despite advances in treatment regimens for cancer, patients suffer from poor prognoses. In this context, the availability of vast natural resources seems to alleviate the shortcomings of cancer chemotherapy. The last decade has seen a breakthrough in the investigations related to the anticancer potential of dietary phytoconstituents. Interestingly, a handsome number of bioactive principles, ranging from phenolic acids, phenylpropanoids, flavonoids, stilbenes, and terpenoids to organosulphur compounds have been screened for their anticancer properties. Among the phenylpropanoids currently under clinical studies for anticancer activity, eugenol is a promising candidate. Eugenol is effective against cancers like breast, cervical, lung, prostate, melanomas, leukemias, osteosarcomas, gliomas, etc., as evident from preclinical investigations. Objective: The review aims to focus on cellular and molecular mechanisms of eugenol for cancer prevention and therapy. Methods: Based on predetermined criteria, various scholarly repositories, including PubMed, Scopus, and Science Direct were analyzed for anticancer activities of eugenol. Results: Different biochemical investigations reveal eugenol inducing cytotoxicity, inhibiting phases of the cell cycles, programmed cell death, and auto-phagocytosis in studied cancer lines; thus, portraying eugenol as a promising anticancer molecule. A survey of current literature has unveiled the molecular mechanisms intervened by eugenol in exercising its anticancer role. Conclusion: Based on the critical analysis of the literature, eugenol exhibits vivid signaling pathways to combat cancers of different origins. The reports also depict the advancement of novel nano-drug delivery approaches upgrading the therapeutic profile of eugenol. Therefore, eugenol nanoformulations may have enormous potential for both the treatment and prevention of cancer.

    Abstract Introduction: Systemic Lupus Erythematous (SLE) is an autoimmune disease, which commonly affects females and is associated with formation of various Antinuclear Antibodies (ANA). Childhood onset SLE has some similarities and differences in immunological profile and clinical manifestations from adult onset SLE patients. Aim: To study the spectrum of clinical manifestation and autoantibody profile of childhood onset SLE patients and to compare with adult SLE patients. Materials and Methods: This was a retrospective observational study conducted from October 2017 to March 2021 in Department of Immunopathology, Institute of Medical Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India. This includes 74 patients of childhood onset SLE and 91 patients of adult SLE. Detailed clinical and laboratory data were collected from medical records. Serum ANA and anti-dsDNA (Deoxyribonucleic Acid) detection was done by solid phase enzyme immunoassay methods. Antibodies to extractable nuclear antigen were detected by dot blot immunoassay. Chi-square test {International Business Machines (IBM) Statistical Package for the Social Sciences (SPSS) version 21.0} was used to compare categorical data of childhood onset SLE and adult SLE patient groups. Results: The mean age of childhood onset SLE patients was 13.05±4.26 years with female:male ratio of 3.93:1. Malar rash (p=0.001) and renal involvement (p=0.021) was significantly more frequent in childhood onset SLE but oral ulcer was significantly more frequent (p=0.038) in adult patients. Anti-ds DNA positivity and reduction in complements C3 and C4 were more commonly seen in childhood onset SLE patients. Conclusion: Age is an important influence on clinical manifestations and autoantibody profile of SLE. Childhood onset SLE showed more frequent renal and skin involvement and more significant activity measured by reduction of complements. Awareness of the same will help our clinicians to detect renal involvement at an early stage and develop organ specific management ...

    Abstract Introduction: Eupatorium adenophorum Spreng. (E. adenophorum) [also known as Ageratina adenophora (Spreng.)] is a perennial and herbaceous invasive plant native to Mexico. Then, in the 1940s, it entered Yunnan Province of China and spread in China, South and South-East Asia. Now it is distributed in different regions of the world. Despite its invasive nature, this plant is used as a traditional medicine in many parts of the world; hence further research works and studies have been conducted to explore potential therapeutic uses of this plant. The main focus of this review is to discuss the existing information of the phytochemistry, pharmacology, traditional uses, as well as toxicity and highlight the prospects for the sustainable use of E. adenophorum. Method: Literature survey was accomplished by using the database including ResearchGate, Science Direct, Web of Science, Google Scholar, PubMed, Scopus, and online books along with some botanical websites. Results: Pharmacological studies of E. adenophorum showed that it poses a wide range of pharmacological properties including antimicrobial, antioxidant, anti-inflammatory, analgesic, insecticidal, larvicidal, and cytotoxic, as well as acaricidal properties based on both in vivo and in vitro studies. More than 95 therapeutically active phytochemical compounds have been screened from the plant. Amongst them, only a small number of phytochemicals have been reported to be pharmacologically active. Conclusion: This review can widen the understanding regarding E. adenophorum and highlight its prospects for further research.

    Abstract Early T precursor acute lymphoblastic leukemia (ETP-ALL) exhibits poor clinical outcomes and high relapse rates following conventional chemotherapeutic protocols. Extensive developmental flexibility of the multipotent ETP-ALL blasts with considerable intra-population heterogeneity in terms of immunophenotype and prognostic parameters might be a target for novel therapeutic interventions. Using a public gene expression dataset (GSE28703) from NCBI GEO DataSets with 12 ETP-ALL and 40 non-ETP-ALL samples, such heterogeneity was found to be reflected in their transcriptome as well. Hub genes were identified from the STRING-derived functional interaction network of genes showing differential expression between ETP-ALL and non-ETP-ALL as well as variable expression across ETP-ALL. Nine genes (KIT, HGF, NT5E, PROM1, CD33, ANPEP, CDH2, IL1B, and CXCL2) among the hubs were further validated as possible diagnostic ETP-ALL markers using another gene expression dataset (GSE78132) with 17 ETP-ALL and 27 non-ETP-ALL samples. Linear dimensionality reduction analysis with the expression levels of the hub genes in ETP-ALL revealed their divergent inclinations towards different hematopoietic lineages, proposing them as novel indicators of lineage specification in the incompletely differentiated ETP-ALL blasts. This further led to the formulation of a personalized lineage score calculation algorithm, which uncovered a considerable B-lineage-bias in a substantial fraction of ETP-ALL subjects from the GSE28703 and GSE78132 cohorts. In addition, STRING-derived physical interactome of the potential biomarkers displayed complete segregation of the B-lineage-skewed markers from other lineage-associated factors, highlighting their distinct functionality and possible druggability in ETP-ALL. A panel of these biomarkers might be useful in pinpointing the dominant lineage specification programmes in the ETP-ALL blasts on a personalized level, urging the development of novel lineage-directed precision therapies as well as repurposing of ...

    Abstract Germ cell tumors (GCT) are an intriguing group of neoplasm having myriad clinical and morphological presentation. More and more transcription factors are being evaluated for identification of same. To study the spectrum of GCTs in a tertiary care center and the use of a stem cell marker OCT4 as a diagnostic adjunct, a retrospective 5-year (2008-2013) study was carried out. Immunohistochemistry (IHC) with OCT4 was performed on all cases and IHC for α feto protein (AFP), CD30, and epithelial membrane antigen (EMA) as per requirement. Cohort included 73 cases (23 males and 50 females). Testicular and ovarian GCTs accounted for 95.83% and 35.71% respectively. In males, seminoma was the commonest (34.78%) followed by mixed GCT (26%). 17.85% of ovarian GCTs were malignant mostly constituted by dysgerminoma (18%). Benign mature cystic teratoma (MCT) constituted 50% of ovarian GCTs. OCT4 immunoexpression was seen in all cases of seminoma/dysgerminoma, embryonal carcinoma, immature teratoma, and seminomatous/embryomatous component of mixed GCTs. Pure yolk sac tumor (YST) and MCT were consistently negative. OCT4 was especially helpful in identification of mixed GCT. A panel of immunohistochemical markers would be a more ideal way to identify and clarify the components because correct identification of the components is important for therapeutic intervention and prognostication. OCT4 being a primordial germ cell marker predicts aggressive behavior and targeted therapy against this should be investigated.

    Abstract Abstract Background The World Health Organization declared the outbreak of the novel coronavirus (COVID-19) as a global health emergency on January 30, 2020, and as a pandemic disease on March 11, 2020. This review highlights the international situation, risk factors, and related protections to be taken as prerequisite measures and probable treatment options for the COVID-19-infected population in the current scenario. Main text The SARS-CoV-2 viruses and their variants caused mild-to-severe respiratory tract infection and used airborne pathways as a way of contagion. Human-to-human transmission led to an exponential growth in the rise in the number of cases making it a real burden to immobilize the rapid spread of the virus while asymptomatic patients created ambiguity for confirmation in the community. It was clear from the case studies of patients that most of them were asymptomatic but still vulnerable to the people around, and hence, in a flash, many countries around the globe went into a complete lockdown, influencing the economy and thrashing industrial outputs. On the other hand, numerous researches were made to counteract the spread through studies in antiviral therapy, immune-based therapy, vaccination development, and natural remedies. Conclusion Although exploration for a specific drug required for the COVID-19 treatment is under extensive research worldwide and some of them are in clinical trial now. Virtual drug library screening is one of the current techniques for repurposing accessible compounds. This review could provide beneficial information about the potential current and future treatment strategies to treat the pandemic COVID-19 infection.

    Abstract Background: Calotropis procera is a large shrub which consists many medicinal properties, used in treatment of snake bite, sinus fistula, rheumatism, mumps, burn injuries, inflammation and jaundice traditionally. All the parts of Calotropis procera were utilized in the treatment of diseases out of which leaves and roots were investigated for its toxicity profile that showed dose dependent toxicity. Toxicity profile of flowers of Calotropis procera was not investigated in the previous studies. The aim of this study was to explore the acute and subacute toxicity of ethanolic extract of Calotropis procera flowers for the safe use of traditional medicine. Method: In acute toxicity, a total of 20 female mice (Swiss albino), weighing between 23 and 32 g were randomly divided into four experimental groups: control, 300, 1000, and 2000 mg/kg groups with 5 mice each, and each received a single dose of extract at 300, 1000, or 2000 mg/kg, respectively. Animals were monitored for 14 days. In the subacute study, a total of 40 mice (23–32 g) were divided into 4 groups, each containing males and females. Group 1 (control group) received vehicle and groups 2, 3, and 4 received extract at doses of 300 mg/Kg, 1000 mg/Kg, 2000 mg/Kg of b.w., respectively, for 28 consecutive days. The study was conducted in compliance with the OECD guidelines 407 and 423. Results: Acute toxicity study showed no mortality at the dose of 2000 mg/Kg. In subacute toxicity study, statistical analysis of hematological and biochemical parameters showed no significant differences compared to control group except marked increase in segmented neutrophils. Histopathological studies revealed no significant structural differences among the treated groups and in comparison to control group. Conclusions: It was concluded that oral administration of doses of ethanolic extract of Calotropis procera flower, administered acutely, did not cause any mortality or notable changes at the dose of 2000 mg/Kg. Therefore, the approximate lethal dose (ALD) of in mice was ...

    Abstract Acetaminophen (APAP) is the most common prescription medicine around the world for the treatment of pain and fever and is considered to be a safe drug at its therapeutic dose. However, a single overdose or frequent use of APAP can cause severe acute liver injury. APAP hepatotoxicity is a prevalent cause of acute liver disease around the world and the lack of suitable treatment makes it a serious problem. In recent years, there has been a surge in interest in using probiotics and probiotic-derived products, known as postbiotics, as health and disease negotiators. A growing body of evidence revealed that they can be equally effective against APAP hepatotoxicity. Different probiotic bacteria were found to be pre-clinically effective against APAP hepatotoxicity. Different postbiotics have also shown exciting results in preclinical models of APAP hepatotoxicity. This review summarized the protective roles and mechanisms of the different probiotic bacteria and postbiotics against APAP hepatotoxicity, with critical discussion. A brief discussion on potential novel probiotics and postbiotics for oxidative liver injury was also included. This review was written in an attempt to pique the interest of researchers in developing a safe therapeutic option against oxidative liver damage using probiotics and/or postbiotics as dietary supplements.
