Forecasting of Indian tourism industry using modeling approach.

Currently, India has become one of the largest economies of the world in which tourism and hospitality have significantly contributed; however, the growth rate of tourism industry has been greatly affected during the COVID-19 pandemic. In this study, we have used the modeling approach to analyze and understand the growth pattern of Indian tourism industry. To achieve this, we consider the data of international tourist arrivals before and after the lockdown. The Dickey-Fuller test, AIC and BIC methods are used to obtain the best fitted model and further, the accuracy of obtained model is also analyzed. Data and forecasting indicate that the weather and public holidays significantly affect the tourism industry.

Plasmodium spp. in macaques, Macaca fascicularis, in Malaysia, and their potential role in zoonotic malaria transmission.

Macaques, Macaca fascicularis, are a known reservoir of Plasmodium knowlesi, the agent of simian malaria which is the predominant zoonotic species affecting humans in Malaysia and other Southeast Asian countries. Recently, a naturally acquired human infection of another simian malaria parasite, P. cynomolgi has been reported. Thus, it is crucial to study the distribution of simian Plasmodium infections with particular attention to the macaques. Four hundred and nineteen (419) long-tailed macaques (Macaca fascicularis) were trapped in selected areas where human cases of P. knowlesi and P. cynomolgi have been reported. Nested polymerase chain reaction (PCR) was conducted to identify the Plasmodium spp., and circumsporozoite protein (CSP) genes of P. knowlesi samples were sequenced. Plasmodium cynomolgi infection was shown to be the most prevalent among the macaque population (68.4%). Although 50.6% of analyzed samples contained single infections either with P. knowlesi, P. cynomolgi, P. inui, P. coatneyi, or P. fieldi, mixed infections with double, triple, quadruple, and all 5 species were also detected. Infection with P. cynomolgi and P. knowlesi were the highest among Malaysian macaques in areas where humans and macaques are in close contact. The risk of zoonotic infection in these areas needs to be addressed since the number of zoonotic malaria cases is on the rise. With the elimination of human malaria, the risk of humans being infected with simian malaria is very high and steps should be taken to mitigate this issue.

Title: Plasmodium spp. chez les macaques, Macaca fascicularis, en Malaisie, et leur rôle potentiel dans la transmission zoonotique du paludisme. Abstract: Les macaques, Macaca fascicularis, sont un réservoir connu de Plasmodium knowlesi, l'agent du paludisme simien qui est l'espèce zoonotique prédominante affectant les humains en Malaisie et dans d'autres pays d'Asie du Sud-Est. Récemment, une infection humaine acquise naturellement par un autre parasite du paludisme simien, P. cynomolgi, a été signalée. Ainsi, il est crucial d'étudier la distribution des infections simiennes à Plasmodium avec une attention particulière pour les macaques. Quatre cent dix-neuf (419) macaques à longue queue (Macaca fascicularis) ont été piégés dans des zones sélectionnées où des cas humains de P. knowlesi et P. cynomolgi avaient été signalés. La réaction en chaîne par polymérase (PCR) nichée a été menée pour identifier les Plasmodium spp. et les gènes de la protéine circumsporozoïte (CSP) des échantillons de P. knowlesi ont été séquencés. L'infection à P. cynomolgi s'est avérée la plus répandue parmi la population de macaques (68,4 %). Bien que 50,6 % des échantillons analysés montraient des infections simples avec soit P. knowlesi, P. cynomolgi, P. inui, P. coatneyi ou P. fieldi, des infections mixtes avec deux, trois, quatre ou même les cinq espèces ont également été détectées. L'infection par P. cynomolgi et P. knowlesi était la plus élevée parmi les macaques malais dans les zones où les humains et les macaques sont en contact étroit. Le risque d'infection zoonotique dans ces zones doit être pris en compte car le nombre de cas de paludisme zoonotique est en augmentation. Avec l'élimination du paludisme humain, le risque d'être infecté par le paludisme simien est très élevé et des mesures doivent être prises pour atténuer ce problème.

Chemical Composition, Cytotoxic and Antibacterial Activities of Essential Oils of Cultivated Clones of Juniperus communis and Wild Juniperus Species.

Needles of seven cultivated clones (C1 - C7) of Juniperus communis at lower altitude and three wild Juniperus species (J. communis, J. recurva and J. indica) at higher altitudes were investigated comparatively for their essential oils (EOs) yields, chemical composition, cytotoxic and antibacterial activities. The EOs yields varied from 0.26 to 0.56% (v/w) among samples. Sixty-one volatile components were identified by gas chromatography-mass spectrometry (GC/MS) and quantified using gas chromatography GC (FID) representing 82.5 - 95.7% of the total oil. Monoterpene hydrocarbons (49.1 - 82.8%) dominated in all samples (α-pinene, limonene and sabinene as major components). Principal component analysis (PCA) of GC data revealed that wild and cultivated Juniperus species are highly distinct due to variation in chemical composition. J. communis (wild species) displayed cytotoxicity against SiHa (human cervical cancer), A549 (human lung carcinoma) and A431 (human skin carcinoma) cells (66.4 ± 2.2%, 74.4 ± 1.4% and 57.4 ± 4.0%), respectively, at 200 µg/ml. EOs exhibited better antibacterial activity against Gram-positive bacteria than against Gram-negative bacteria with the highest zone of inhibition against Staphylococcus aureus MTCC 96 (19.2 ± 0.7) by clone-7. As per the conclusion of the findings, EOs of clone-2, clone-5 and clone-7 can be suggested to the growers of lower altitude, as there is more possibility of uses of these EOs in food and medicinal preparations.

Crystal Nucleation of Tolbutamide in Solution: Relationship to Solvent, Solute Conformation, and Solution Structure.

The influence of the solvent in nucleation of tolbutamide, a medium-sized, flexible and polymorphic organic molecule, has been explored by measuring nucleation induction times, estimating solvent-solute interaction enthalpies using molecular modelling and calorimetric data, probing interactions and clustering with spectroscopy, and modelling solvent-dependence of molecular conformation in solution. The nucleation driving force required to reach the same induction time is strongly solvent-dependent, increasing in the order: acetonitrile

Prevalence and predictors of metabolic syndrome in patients with schizophrenia and healthy controls: A study in rural South Indian population.

INTRODUCTION: Metabolic syndrome (MetS) has been extensively studied as a co-morbidity in patients with schizophrenia. A disparity is noted between hospital and community based estimates in India. We aimed to examine the prevalence and predictors of MetS in schizophrenia patients and general population controls in a rural population in South India. METHODS: Patients (n=157) and general population controls (n=263) were recruited from a rural area in South India. Diagnosis of MetS was established using International Diabetes Federation (IDF) criteria. Patients were also assessed on clinical parameters, treatment details, dietary and physical activity patterns. Predictors of MetS were estimated based on subgrouping of patients with and without MetS. RESULTS: 50 (31.8%) of the patients and 76 (28.9%) of the controls were diagnosed to have MetS. Female gender and ongoing antipsychotic exposure were noted to be significant predictors of MetS with odds ratio (95% confidence interval) of 2.87 (1.2-6.86) and 4.42 (1.37-14.25) respectively. Three empirically defined treatment groups 'never treated', 'ever treated' and 'continuous treatment' groups had odds ratios (95% CI) of 0.53 (1.68-6.58), 0.92 (0.5-1.69) and 3.33 (1.68-6.58) when compared to the control group. CONCLUSIONS: Patients who were naïve to antipsychotics had a significantly lower prevalence of MetS compared to general population. This finding doesn't support the antipsychotic independent risk for MetS in patients with schizophrenia. Female gender and regular antipsychotic exposure predicted MetS.

Quercetin does not alter the oral bioavailability of Atorvastatin in rats.

The study was undertaken to evaluate the effect of Quercetin on the pharmacokinetics of Atorvastatin Calcium. In-vivo Pharmacokinetic studies were performed on rats in a single dose study and multiple dose study. Rats were treated with Quercetin (10 mg/kg) and Atorvastatin Calcium (20 mg/kg) orally and blood samples were collected at (0) pretreatment and 0.5, 1, 1.5, 2, 2.5, 3, 4, 8, 12, 24 hours post treatment. Plasma concentrations of Atorvastatin were estimated by HPLC method. Quercetin treatment did not significantly alter the pharmacokinetic parameters of atorvastatin like AUC(0-24), AUC(0-α) , T(max), C(max) and T(½) in both single dose and multiple dose studies of Atorvastatin Calcium. Quercetin does not alter the oral bioavailability of Atorvastatin Calcium in rats.

Clipping the (tongue) tie.

Ankyloglossia is an uncommon congenital oral anomaly that can cause difficulty with breast-feeding and speech articulation. For many years, the subject of ankyloglossia has been controversial with practitioners of many specialties having widely different views regarding its significance and management. This study is about a series of five cases of ankyloglossia subjected to surgical correction by frenectomy procedure. Three cases were treated with electrocautery, one case with diode laser and one case with conventional scalpel technique. 1 week and 1 month post-operative follow-ups were done and healing was compared with the available literature. Manipulation of tissues was better in laser and electrocautery techniques when compared with scalpel. Post-operative complication of swelling and pain was seen in scalpel technique whereas it was largely uneventful in other techniques. Though, there was no difference in healing at the end of first month clinically, scalpel technique has shown better results in organization of muscle fibers. This clinical study indicates that laser and electrocautery treatment used for frenectomy operations provides better patient perception in terms of postoperative pain and function than that obtained by the scalpel technique. Considering the above advantages, when used correctly, the laser and electrocautery offers a safe, effective, acceptable and impressive alternative for frenectomy operations.

KAP study conducted to assess the impact of special health education campaign for control of dengue at Vellore in Tamil Nadu.

An abnormal increase in the incidence of dengue was reported at Vellore Corporation since September 2012. Intensive control operations supported with health education campaigns were carried out from September to November 2012 till the outbreak situation subsided. During December 2012, a cross sectional survey was conducted at Vellore Corporation to assess the impact of the health education campaigns on the knowledge, attitude and practice in the community and also to assess future needs. A total of 101 families from four different locations at Vellore corporation were interviewed on pre-structured formats. Though 80% of the respondents felt that dengue could be effectively prevented and controlled only with community participation, majority of them lacked awareness on the day time biting behaviour of Aedes mosquitos, their indoor resting and breeding habits and relevance of specific control measures focused on the bionomics of dengue vectors.
