Association of obesity and thyroid cancer at a tertiary care hospital in Pakistan
Objective: Thyroid cancer (TC) is one of the most common endocrine malignancies with a rapidly increasing worldwide presence. In Pakistan, it is more prevalent in females than males and has an incidence rate of 2.1%. Obesity and excess body mass index (BMI) has been linked to several cancers and is thought to be a risk factor for TC. We aim to investigate the incidence of TC in our population and understand it\u27s correlation with obesity. Subjects: The study was a retrospective case series conducted in the years 2000 to 2014, at the Aga Khan University Hospital (AKUH), Karachi, Pakistan where 156 patients who had been diagnosed and treated for TC were analyzed. Clinicopathological data was collected from medical records of these patients and weight and height were measured, pre-surgery, post-surgery, and at follow up. The BMI was correlated with patient variables for any significant associations. Results: The patient set comprised of 38.5% males and 61.5% females with a mean age of 47.77 (SD ± 14.35). The BMI was significantly associated with age as 72.8% of participants were obese and \u3e45 years old as compared to 27.2% who were under 45 years and obese (p-value0.999). Conclusion: The majority of-of TC patients among the Pakistani population were obese and female. Age was significantly associated with the risk of having a higher BMI. Moreover, differences in BMI pre and post-surgery could not be statistically proven
Identification of immune biomarkers in recent active pulmonary tuberculosis
Tuberculosis (TB) has remained an unsolved problem and a major public health issue, particularly in developing countries. Pakistan is one of the countries with the highest tuberculosis infection rates globally. However, methods or biomarkers to detect early signs of TB infection are limited. Here, we characterized the mRNA profiles of immune responses in unstimulated Peripheral blood mononuclear cells obtained from treatment naïve patients with early signs of active pulmonary tuberculosis without previous history of clinical TB. We identified a unique mRNA profile in active TB compared to uninfected controls, including cytokines such as IL-27, IL-15, IL-2RA, IL-24, and TGFβ, transcription factors such as STAT1 and NFATC1 and immune markers/receptors such as TLR4, IRF1, CD80, CD28, and PTGDR2 from an overall 84 different transcripts analyzed. Among 12 significant differentially expressed transcripts, we identified five gene signatures which included three upregulated IL-27, STAT1, TLR4 and two downregulated IL-24 and CD80 that best discriminate between active pulmonary TB and uninfected controls with AUC ranging from 0.9 to 1. Our data identified a molecular immune signature associated with the early stages of active pulmonary tuberculosis and it could be further investigated as a potential biomarker of pulmonary T
Expression profile of KIR3DS1/KIR3DL1 receptors in association with immunological responses in TB, HIV and HIV/TB infected patients
Several studies investigated KIR3DS1 and KIR3DL1 in the context of various infections. However, none of the studies were performed on KIR3DS1/L1 in association with IFN-É£/IL-10 in TB, HIV-1, and their confections. We aimed to evaluate KIR3DS1/KIR3DL1 expression in association with IFNÉ£/IL-10 in HIV-1 and TB mono-infections and HIV-1/TB confection and compared with uninfected controls using RTq PCR. We also performed correlation analysis between KIR3DS1, KIR3DL1, IFN-É£ and IL-10 in the respective cohorts. The overall expression of KIR3DS1 was found to be downregulated in all groups, whereas in HIV-1 and HIV-1/TB, the frequency of KIR3DS1(+) expression was significantly (p \u3c 0.05) associated with undetected HIV-1 viral load. However, expression of KIR3DL1 was found to be significantly (p \u3c 0.05) upregulated in HIV-1 only. In addition, IFNÉ£ expression was significantly (p \u3c 0.05) decreased in TB, whereas in HIV-1/TB, IFNÉ£ expression was significantly (p \u3c 0.05) increased. In contrast, IL-10 expression was significantly (p \u3c 0.05) increased in HIV-1 and HIV-1/TB but not in TB. Also, we found significant positive correlation (p \u3c 0.05, r = 0.61) between KIR3DL1 and IFNÉ£ expression in TB and negative correlation (p \u3c 0.05, r = - 0.62) between KIR3DS1 and IL-10 in HIV-1/TB. In conclusion, we suggest that expression of KIR3DS1/L1 is associated with IFNÉ£/IL-10 responses and it is involved in modulating disease severity in HIV-1 and TB infection
Inhibitory Potential of Combination of Macrolide Antibiotic with Conventional Chemotherapeutic Agent Sorafenib on Growth Rate of Cancer Cell Population
Over the past few years great progress has been achieved in anticancer therapy, but development
of resistance and unavoidable side effects have incapacitated these fulfilments. Keeping in view
this demanding condition, numerous drugs with unique antitumor mechanisms are under
investigations including antimicrobials which have been shown to possess anti-inflammatory,
immunomodulatory and cytotoxic effects. In this regard, both conventional and novel antimicrobials
are being studied to explore their anticancer potential along with underlying mechanisms which
may render them as effective anticancer drugs in near future. Moreover, the new approach of drug
repurposing is also being encouraged especially in cancers in order to reduce cost and limit adverse effects. In recent times a cumulative number of studies have laid stress upon the antitumor
properties of antimicrobials. Consequently, this study has been conducted to see comparative
inhibitory effect of Sorafenib and its combination with a macrolide antibiotic Azithromycin on growth
rate HepG2 cell line
A New 2D Metal-Organic Framework for Photocatalytic Degradation of Organic Dyes in Water
Two-dimensional (2D) metal-organic frameworks (MOFs) are fascinating photocatalytic materials because of their unique physical and catalytic properties. Herein, we report a new (E)-4-(3-carboxyacrylamido) benzoic acid [ABA–MA] ligand synthesized under facile conditions. This ABA–MA ligand is further utilized to synthesize a copper-based 2D MOF via the solvothermal process. The resulting 2D MOF is characterized for morphology and electronic structural analysis using advanced techniques, such as proton nuclear magnetic resonance, Fourier-transform infrared spectroscopy, ultraviolet-visible spectroscopy, and scanning electron microscopy. Furthermore, 2D MOF is employed as a photocatalyst for degrading organic dyes, demonstrating the degradation/reduction of methylene blue (MeBl) dye with excellent catalytic/photodegradation activity in the absence of any photosensitizer or cocatalyst. The apparent rate constant (kap) values for the catalytic degradation/reduction of MeBl on the Cu(II)–[ABA-MA] MOF are reported to be 0.0093 min−1, 0.0187 min−1, and 0.2539 min−1 under different conditions of sunlight and NaBH4. The kinetics and stability evaluations reveal the noteworthy photocatalytic potential of the Cu(II)–[ABA–MA] MOF for wastewater treatment. This work offers new insights into the fabrication of new MOFs for highly versatile photocatalytic applications
