Immunization of Children in a Rural Area of North Kashmir, India: A KAP Study.
Background: Knowledge, attitude and practices about immunization among mothers of children aged 1-2 years was assessed. Method: 300 mothers were administered a semi-structured questionnaire at PHC Hajan from 1st march to 1st may 2011 to elicit the information about the knowledge, attitude and practices of the mothers regarding immunization. Results: 100% of mothers knew that vaccination is beneficial and protects their children from diseases. 39% knew OPV protects from polio while only 1% were aware of protective role of BCG. All mothers knew about immunization in pregnancy but 86% were unaware about its preventive role. 26% mothers believed that 3 doses of T.T (tetanus toxoid) are to be given during pregnancy. Whereas 98% of children were completely immunized, 93% completed on schedule. Eighty percent of mothers reported of fever following DPT. All mothers had received tetanus toxoid during pregnancy. Conclusion: Considering mothers' poor knowledge and good attitude, health education on immunization is emphasized to improve their practices
GABAergic excitation in the basolateral amygdala
GABA-containing interneurons are a diverse population of cells whose primary mode of action in the mature nervous system is inhibition of postsynaptic target neurons. Using paired recordings from parvalbumin-positive interneurons in the basolateral amygdala, we show that, in a subpopulation of interneurons, single action potentials in one interneuron evoke in the postsynaptic interneuron a monosynaptic inhibitory synaptic current, followed by a disynaptic excitatory glutamatergic synaptic current. Interneuron-evoked glutamatergic events were blocked by antagonists of either AMPA/kainate or GABA(A) receptors, and could be seen concurrently in both presynaptic and postsynaptic interneurons. These results show that single action potentials in a GABAergic interneuron can drive glutamatergic principal neurons to threshold, resulting in both feedforward and feedback excitation. In interneuron pairs that both receive glutamatergic inputs after an interneuron spike, electrical coupling and bidirectional GABAergic connections occur with a higher probability relative to other interneuron pairs. We propose that this form of GABAergic excitation provides a means for the reliable and specific recruitment of homogeneous interneuron networks in the basal amygdala
Fluctuation induces evolutionary branching in a modeled microbial ecosystem
The impact of environmental fluctuation on species diversity is studied with
a model of the evolutionary ecology of microorganisms. We show that
environmental fluctuation induces evolutionary branching and assures the
consequential coexistence of multiple species. Pairwise invasibility analysis
is applied to illustrate the speciation process. We also discuss how
fluctuation affects species diversity.Comment: 4 pages, 4 figures. Submitted to Physical Review Letter
Mapping and Assessing Fire Damage on Broadleaved Forest Communities in Big Cypress National Preserve
Within Big Cypress National Preserve (BICY), oak-dominated forests and woodlands as well as tropical and temperate hardwood hammocks are integral components of the landscape and are biodiversity hotpots for both flora and fauna. These broadleaved forest communities serve as refugia for many of the Preserve’s wildlife species during prolonged flooding and fires. However, both prolonged flooding and severe fires, which are important and necessary disturbance vectors within this landscape, can have deleterious effects on these forested communities. This is particularly true in the case of fires, which under extreme conditions associated with drought and elevated fuel loads, can burn through these forested communities consuming litter and understory vegetation and top killing most, if not all, of the trees present
Tree Mortality following Prescribed Fire and a Storm Surge Event in Slash Pine (Pinus elliottii var. densa) Forests in the Florida Keys, USA
In fire-dependent forests, managers are interested in predicting the consequences of prescribed burning on postfire tree mortality. We examined the effects of prescribed fire on tree mortality in Florida Keys pine forests, using a factorial design with understory type, season, and year of burn as factors. We also used logistic regression to model the effects of burn season, fire severity, and tree dimensions on individual tree mortality. Despite limited statistical power due to problems in carrying out the full suite of planned experimental burns, associations with tree and fire variables were observed. Post-fire pine tree mortality was negatively correlated with tree size and positively correlated with char height and percent crown scorch. Unlike post-fire mortality, tree mortality associated with storm surge from Hurricane Wilma was greater in the large size classes. Due to their influence on population structure and fuel dynamics, the size-selective mortality patterns following fire and storm surge have practical importance for using fire as a management tool in Florida Keys pinelands in the future, particularly when the threats to their continued existence from tropical storms and sea level rise are expected to increase
Seasonal and Altitudinal Prevalence of Fascioliasis in Buffalo in Eastern Nepal
Buffalo is the most important livestock commodities for milk, meat production and several other multipurpose uses distributed densely from southern tarai to northern mid-hills in Nepal. Among several internal parasitic diseases fascioliasis is highly economic one caused by Fasciola in buffaloes. However, there are only few studies carried on prevalence of fascioliasis emphasizing buffaloes in relation to seasonal (summer and rainy, and winter) and altitudinal variations. Therefore, we examined prevalence of fascioliasis seasonally and vertically. For the purpose, we selected two districts of eastern Nepal and sampled from low altitude area known as Madhesha ranging from 175-200, Dhankuta from 800-1200 m, and Murtidhunga from 1800-2200 m elevation from the sea level, representing tarai, mid hills and high hills, respectively. Altogether from February 2013 to January 2014 at every two months interval we collected 798 fecal samples from buffaloes; 282 from Murtidhunga, 239 from Dhankuta and 277 from Madhesha. The samples were examined microscopically for the presence of Fasciola eggs using sedimentation technique. Results showed that overall prevalence of fascioliasis in buffaloes was 39.9% (319/798), ranging highest 42.6%in Madhesha followed by 39.7% in Murtidhunga and 37.2% in Dhankuta, respectively. The prevalence of fascioliasis was found to be significantly (p <0.05) high in winter (44.9%) comparing to rainy season (34.4%). The prevalence of fascioliasis in buffaloes was relatively higher in low altitude than high altitude, although it was not statistically significant (p <0.05). In our findings the female buffaloes showed higher prevalence for fascioliasis than in male. Since the fascioliasis in buffaloes is highly endemic, thus strategic deworming in high risk period is recommended along with measure to prevent pasture contamination with buffalo feces
Conducting qualitative interviews using virtual communication tools amid the COVID-19 pandemic: A learning opportunity for future research
The COVID-19 pandemic has threatened the health and wellbeing of the global citizens which has led to a significant change in attitude, lifestyle and behaviour of people from diverse professions, including academics and researchers. Doctoral students and funded researchers with the time limit to their research project have experienced stress and anxiety due to the struggle of negotiating and managing timeline to complete the fieldwork for their research. In the current circumstances, increasing number of researchers are looking for alternative methods to conduct the fieldwork and complete the data collection. In this context, the aim of this viewpoint is to provide reflections on the challenges and opportunities experienced by the authors while conducting qualitative research fieldwork during the COVID-19 pandemic
