Epidemiological study of neural tube defects in Jammu division, India

Background: Prevalence and spectrum of neural tube defects has undergone seasonal and secular variations in different regions of the world since the turn of last century. However precise etiology inspite of lot of research has not been clearly elucidated.Methods: The study was conducted in Government Medical College Hospital and SMGS Hospital Jammu in patients diagnosed to have a neural tube defect from birth to 19 years. History regarding sociodemographic profile, antenatal history and significant birth history was elicited. Complete general physical examination, Local examination of the lesion was carried out and neural tube defects were classified. All the cases were subjected to ultrasound head to determine ventricular size and rule out hydrocephalus. The data was entered in Microsoft Excel and results were presented in form of percentages and proportions.Results: Maximum children admitted were in the age group of <1 month and belonged to Jammu district. Commonest anomaly seen was lumbosacral meningomyelocele with associated hydrocephalus and neural deficit. Mothers who gave birth to an NTD affected child were commonly in the age group of 20-30 years, with commonest NTD affected sib being 1stborn and most of parents being from very low socio-economic strata of society. Only 7 mothers had received antenatal advice with ultrasound and almost none had received folic acid either before or after conception.Conclusions: Neural tube defects appear to be fairly common anomaly among females of lower socioeconomic strata, living in far flung mountainous regions of the state, devoid of proper health care facilities and education

Performance of Chilli (Capsicum annuum L.) hybrids for yield and quality traits

Twenty-eight F1 combinations of chilli (Capsicum annuum L.) obtained from half-diallel cross along with eight diverse parents were evaluated in a field study to elucidate the information on the extent of mean performance of various horticultural traits. The analysis revealed that all the genotypes possessed wide spectrum of variability and showed significant differences for parents and hybrids for the traits studied. For parents UHF CHI 13 (216.20), UHF CHI 15 (193.80), UHF CHI 5 (139.00) and for hybrids H1 (182.60), H9 (181.40) and H7 (172.80) hold highest fruit count per plant. The parents UHF CHI 5 (1047.13 g), UHF CHI 15 (949.62 g) and UHF CHI 7 (912.61 g) and cross combinations H17 (1535.10 g), H8 (1320.00), H6 (1229.76) and H18 (967.60) recorded the high ripe fruit yield per plant. As for earliness, parents UHF CHI 5 (43.33), UHF CHI 11 (45.00), UHF CHI 7 (45.33) and hybrids H27 (42.67), H26 (43.00) and UH28 (43.00) took minimum days for flowering. For pungency UHF CHI 12 (0.28 %), UHF CHI 13 (0.26 %), DKC-8 (0.24 %) and H23 (0.33 %), H5 (0.31 %), H26 (0.26 %) recorded high capsaicin content

Characterization of Lens Based Photoacoustic Imaging System

Some of the challenges in translating photoacoustic (PA) imaging to clinical applications includes limited view of the target tissue, low signal to noise ratio and the high cost of developing real-time systems. Acoustic lens based PA imaging systems, also known as PA cameras are a potential alternative to conventional imaging systems in these scenarios. The 3D focusing action of lens enables real-time C-Scan imaging with a 2D transducer array. In this paper, we model the underlying physics in a PA camera in the mathematical framework of an imaging system and derive a closed form expression for the point spread function (PSF). Experimental verification follows including the details on how to design and fabricate the lens inexpensively. The system PSF is evaluated over a 3D volume that can be imaged by this PA camera. Its utility is demonstrated by imaging phantom and an ex vivo human prostate tissue sample

Testicular microlithiasis imaging and follow-up: guidelines of the ESUR scrotal imaging subcommittee

The subcommittee on scrotal imaging, appointed by the board of the European Society of Urogenital Radiology (ESUR), have produced guidelines on imaging and follow-up in testicular microlithiasis (TML)
