Introduction: Neonatal period is the most susceptible period of life due to different causes, which in most cases are preventable. Every year millions of neonates are born and a large proportion of them are admitted to the neonatal intensive care unit (NICU) for various indications. One of the Millennium Development Goals is to reduce under five mortality by two thirds by 2015. Therefore, this study was conducted to identify the clinical profile, pattern of diseases and common causes of mortality and morbidity in neonates admitted to NICU. Materials and Methods: A retrospective study was conducted at level III Neonatal NICU of a tertiary -care teaching hospital from January, 2012 to December, 2012. Results: Total of 361 neonates were admitted in NICU. Eighty six neonates (23.8%) were admitted due to prematurity and 73 (20.2%) with birth asphyxia. Among birth asphyxia, 40(54.8%)were in HIE III, 27.4% and 17.8% in HIE II and HIE I, respectively. One hundred eighteen (32.6%) cases were diagnosed as sepsis. The overall mortality was 20.2% during hospital stay. Conclusions: Sepsis, prematurity and birth asphyxia were major causes for admission in NICU. All these etiologies are preventable up to some extent and, if detected earlier, can be effectively treated in order to reduce morbidity and mortality.

Introduction:Intestinal parasitic infestation is a major public health problem in children of developing countries Because of poor socio-economic conditions and lack of good hygienic living. The aims of this study were to measure the prevalence of intestinal parasitic infestations and to identify risk factors associated with parasitic infestations among the school children of Itahari Municipality.Materials and Methods:The cross-sectional study was conducted in Grade VI, VII and VIII in Government and private schools of Itahari Municipality. Stratified random sampling method was applied to choose the schools and the study subjects. Semi-structured questionnaire was administered to the study subjects and microscopic examination of stool was done. The Chi-square test was used to measure the association of risk factors and parasitic infestation.Results:Overall intestinal parasitic infestation was found to be 31.5%. Around 13% of the study population was found to be infested with helminthes and 18.5% of the study population was protozoa infected. Not using soap after defecation, not wearing sandals, habit of nail biting and thumb sucking were found to be significantly associated with parasitic infection.Conclusions:The prevalence of intestinal parasitic infestation was found to be high in school children of Itahari. Poor sanitary condition, lack of clean drinking water supply and education is supposed to play an important role in establishing intestinal parasitic infections.

Induced mutagenesis is one of the most effective strategies for trait improvement without altering the well-optimized genetic background of the cultivars. In this review, several currently accessible methods such as physical, chemical and insertional mutagenesis have been discussed concerning their efficient exploration for the tomato crop improvement. Similarly, challenges for the adaptation of genome-editing, a newly developed technique providing an opportunity to induce precise mutation, have been addressed. Several efforts of genome-editing have been demonstrated in tomato and other crops, exploring its effectiveness and convenience for crop improvement. Descriptive data compiled here from such efforts will be helpful for the efficient exploration of technological advances. However, uncertainty about the regulation of genome-edited crops is still a significant concern, particularly when timely trait improvement in tomato cultivars is needed. In this regard, random approaches of induced mutagenesis are still promising if efficiently explored in breeding applications. Precise identification of casual mutation is a prerequisite for the molecular understanding of the trait development as well as its utilization for the breeding program. Recent advances in sequencing techniques provide an opportunity for the precise detection of mutagenesis-induced sequence variations at a large scale in the genome. Here, we reviewed several novel next-generation sequencing based mutation mapping approaches including Mutmap, MutChromeSeq, and whole-genome sequencing-based mapping which has enormous potential to accelerate the mutation breeding in tomato. The proper utilization of the existing well-characterized tomato mutant resources combined with novel mapping approaches would inevitably lead to rapid enhancement of tomato quality and yield. This article provides an overview of the principles and applications of mutagenesis approaches in tomato and discusses the current progress and challenges involved in tomato mutagenesis research.

Objective: To study the clinical presentation, investigational profile and outcome of neonatal sepsis in general and with special reference to inborn (intramural) or out born (extramural), sex and weight of the neonate. Materials and method: Retrospective descriptive study of neonates admitted during 2 years from July 2007 to June 2009 in special care neonatal unit of the department of Pediatrics, College of Medical Sciences-Teaching Hospital, Bharatpur, Nepal. Results: Majority of neonates were out born and referred (72.2%) to this institution. Significant number of babies was having sepsis in out born group (59%) as compared to inborn (35%). Male sex was found to have more sepsis as compared to female. Sepsis was observed to be inversely related to birth weight, 65% in low birth weight (LBW, <2.5Kg) as compared to 42.6% in normal birth weight group (> 2.5kg). Conclusions: High index of suspicion for diagnosis of neonatal sepsis is required especially in the presence of risk factors. Prevalence of sepsis is inversely related to birth weight. More number of out born delivered babies developed sepsis. Neonatal sepsis related morbidity and mortality can be significantly reduced by comprehensive obstetric and neonatal care at multiple levels right from community to health institutions. Key words: Neonatal sepsis; Inborn; Out born; Low birth weight (LBW). DOI: 10.3126/jcmsn.v6i2.3609   Journal of college of Medical Sciences-Nepal, 2010, Vol.6, No-2, 1-6

Fast neutron (FN) radiation mediated mutagenesis is a unique approach among the several induced mutagenesis methods being used in plant science in terms of impacted mutations. The FN mutagenesis usually creates deletions from few bases to several million bases (Mb). A library of random deletion generated using FN mutagenesis lines can provide indispensable resources for the reverse genetic approaches. In this review, information from several efforts made using FN mutagenesis has been compiled to understand the type of induced mutations, frequency, and genetic stability. Concerns regarding the utilization of FN mutagenesis technique for a plant with different level of ploidy and genome complexity are discussed. We have highlighted the utility of next-generation sequencing techniques that can be efficiently utilized for the characterization of mutant lines as well as for the mapping of causal mutations. Pros and cons of mapping by mutation (MutMap), mutant chromosome sequencing (MutChromSeq), exon capture, whole genome sequencing, MutRen-Seq, and different tilling approaches that can be used for the detection of FN-induced mutation has also been discussed. Genomic resources developed using the FN mutagenesis have been catalogued wooing to meaningful utilization of the available resources. The information provided here will be helpful for the efficient exploration for the crop improvement programs and for better understanding of genetic regulations.
