ABSTRACT
Objective:To explore the damage of panretinal photocoagulation (PRP) to the subbasal nerve plexus (SNP) and its related mechanisms by comparing SNP changes in wide-field mosaic between before and after PRP treatment in diabetic patients.Methods:A randomized controlled study was conducted.Fifty-seven patients (114 eyes) with type 2 diabetes mellitus and binocular diabetic retinopathy (DR) stage IV to receive PRP treatment in Shanxi Eye Hospital from April to November 2019 were enrolled.The subjects were randomly divided into horizontal-vertical laser group and vertical-horizontal laser group according to a random number table.Twenty-nine eyes from 29 patients were assigned to the horizontal-vertical laser group with the photocoagulation sequence of temporal-nasal-inferior-superior.Twenty-eight eyes from 28 patients were assigned to the vertical-horizontal laser group with the photocoagulation sequence of inferior-superior-temporal-nasal.The severer eyes of each subject were chosen as the treatment eye and the contralateral eyes were chosen as the control eye.Corneal confocal laser scanning microscopy (CCM) was performed before PRP treatment, 1 week after each photocoagulation, and 1 month after the completion of PRP treatment to collect images of the SNP over an area of 2-3 mm around the whorl-like pattern.Captured images at each time were merged into one image by using the Photoshop CC 2017 image processing software, and then the nerve fiber length (NFL) of whorl-like pattern was measured by Neuron J image analysis software.McGill pain questionnaire was used to investigate the pain of patients after each photocoagulation.The NFL changes of SNP at different time points were compared between different eyes and different photocoagulation sequence groups.The study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Shanxi Eye Hospital (No.201804b). Written informed consent was obtained from each patient prior to entering the study cohort.Results:After PRP treatment, there were different degrees of neural structure loss of SNP nerve fibers in 11 treatment eyes, but there was no significant change in SNP nerve fibers in the control eyes.There were significant differences in NFL between the treatment eyes and the control eyes at various time points ( Feyes=2.020, P=0.039; Ftime=4.062, P=0.001). In the horizontal-vertical laser group, different degrees of neural structure loss on the photocoagulation side were found in SNP nerve fibers after the first and second photocoagulation.In the vertical-horizontal laser group, different degrees of neural structure loss on the photocoagulation side were found in SNP nerve fibers after the third and fourth photocoagulation.There was no significant difference in NFL of treatment eyes between the two groups ( Fgroup=0.099, P=0.754), but there was a significant difference in NFL at various time points before and after treatment ( Ftime=5.231, P<0.001). There were 9 (9/57) patients who complained of pain after PRP, which occurred at the first time of photocoagulation in 7 of them. Conclusions:SNP damage may occur after PRP in patients with DR, and SNP is prone to be damaged on the photocoagulation side when performing horizontal photocoagulation.

ABSTRACT
Dermatoglyphics is the study of finger print patterns and the term was coined by Harold Cummins in 1926. Finger prints are imprints of epidermal ridges, which are formed in early embryonic life, during 10th to 16th week of intrauterine life and remain permanent during whole life. Dermatoglyphic patterns have polygenic inheritance and are affected by environmental factors in the uterus. Finger print patterns are mainly of three types: arches whorls and loops; though there are more than 100 ridge characteristics, called Galton’s details, in a single rolled finger print. Dermatoglyphics is not only used in the identification of an individual but also serves as a mirror of one’s potential and talent. In this review, we will be discussing Dermatoglyphics and its important role in the diagnosis of chromosomal disorders and other diseases which have some genetic bases.
ABSTRACT
Maize (Zea mays L.) being the highest yielding cereal crop in the world is of significant importance for countries like India, where rapidly increasing population already out stripped the available food supplies. Maize crop possesses great genetic diversity. Maize Plant is attacked by 140 species of insects causing varying degree of damage causing an annual loss of over 1 billion in the Semi Arid Tropics (ICRISAT, 1992). Out of these, only 10 species cause serious damage from sowing till storage, of which the stemborer Chilo partellus (Swinhoe) is the major one (Hiremath et al., 1988). The larvae of C.partellus after hatching feed on soft surface of the leaves and then enter the stem through whorl of feeding on the pith of the stem. The growth of the plants becomes shunted and resulting in dead hearts when attacked by C.partellus at their initial stages. The larvae transferred from other plants enter the stem through lower nodes by making the holes. Stem borers pupate inside the stem. They make holes before pupation for the emergence of adults. Since host plant resistance is the back bone of Insect Pest Management; hence the present investigation was initiated. Present studies were designed to identify maize genotype resistance against stem borer in order to minimize pesticide use, improve natural balance, and enhance the activity of bio control agents, and to increase crop production. The investigations were carried out on the screening of Maize genotypes against Maize stem borer Chilo partellus in kharif season were conducted on the agricultural farm of the institute of Agricultural Sciences, Banaras Hindu University, Varanasi during kharif season of 2010-2011 to screen the relative resistance /susceptibility of 19 genotypes of maize to the insect pest, maize stem borer (Chilo partellus). In order to screen the relative susceptibility of different maize genotypes to maize stem borer the following genotypes were screened under field conditions. The symbols T1 to T19 have been used to represent the following cultivars of maize. HUZM 217, HUZM 185, HUZM 227, HUZM 186, AH 411, NMH 9858, HUM 152, CM 119, QPM 466, QPM 467, QPM 169, QPM 193, QPM 163, HUZQPM 240, HUZQPM 241, HUZQPM 242, HUZQPM 243, HUZQPM 246, HUZQPM 247. The maize varieties were grown in plots having 19 rows, plot size 13x2.5 m². The plant spacing between rows and plants were maintained 70 cm and 20 cm, respectively. The crop was grown as per the normal agronomic practices during the kharif season of 2010-2011. The effect of natural infestation was studied. The crop was sown on 22nd July 2010 and harvested on 10th November 2010. Entire screening was based on leaf damage, dead heart formation, no. of exit holes. No. of larvae and pupae population and mean tunnel length. Dead heart formations were higher in more susceptible genotypes than least susceptible genotypes. There were no sign of dead heart was found in cultivar HUZQPM 242, HUZQPM 246, QPM 193, CM 119, AH 411, HUM 152, NMH 9858, HUZM 185, HUZM 217. Maximum occurrences of dead heart were in cultivar HUZM 227, QPM 169. Leaf damage was measured on visual rating scale. In context of leaf injury rating mean was 2.6 to 6.6. Maximum leaf damage was reported on cultivar QPM 169.Average plant height was mean of length from root to flag leaf. Mean tunnel length was divided into three categories-Least susceptible (0-5cm), moderately susceptible (5-10cm), highly susceptible (>10 cm) and respected genotypes also have been identified.
ABSTRACT
Dermatoglyphics, the study of fingerprints are constant and individualistic. The ridge pattern depends upon cornified layer of epidermis as well as dermal papillae. This study was conducted to correlate between digital dermatoglyphics patterns in ABO, Rh blood groups and evaluates their significance. A total of 200 first year MBBS students with known blood groups from 2004 and 2005 batch of IGGMC, Nagpur were included in the study. Fingerprints were obtained by printing method. Parameters studied were arches, whorls, loops. It was concluded that, whorls were highest in B blood group and the difference was significant with O blood group. Loops were highest in O blood group and were significant with A, B, AB blood groups. Arches were highest in AB blood group and were statistically significant with B and O blood groups. Arches were higher in Rh negative blood group differing statistically with Rh positive blood group.

Since the beginning of criminal investigation, police have sought an infallible means of human identification. Many criteria were used by for purpose of identification like race, sex, age, complexion, hair, deformity, scar, tattoo, footprint and occupation marks but fingerprint is found to be the most reliable. The present study was aimed to know distribution of various patterns of left hand thumb imprints among IInd year MBBS students. The present study was conducted on 81 Medical Students of Pramukh Swami Medical College, Karamsad (Gujarat) to determine patterns of left hand thumb imprints. 47 males and 34 females were included for the study and left hand thumb imprints were taken from all by using rolling on method. The most frequent thumb imprint pattern was loop in males and whorls in female. Overall, almost equal distribution of loops and whorls pattern was observed. All cases of thumb imprints were matched.
ABSTRACT
Left handedness is known to be related with inheritance and is different from right handedness in brain development and various aspects of perceptive and cognitive performance. Fingerprints are also related with inheritance and do not change for the whole life. In addition, individuals have different fingerprints. The aim of the present study was to identify genetic correlation between fingerprints and handedness by examining how different fingerprints are between left handers and right handers. The study group to imprint fingerprints was composed of 55 left handers and 144 right handers of 1063 college students. The reliability of handedness assessment tool was Cronbach's alpha=0.948. The imprinted fingerprints were classified by fingerprint type (arch, radial loop, ulnar loop, whorl). Finger ridges and triradii in fingerprints were also counted. We performed frequency analysis, reliability analysis, cross-tabs analysis, chi-square test, independent t-test, paired t-test by SPSS win 15.0 for the data. The left handed males and females exhibited more arch types than the right handers and less whorl types than the right handers. The left handers in both hands exhibited more arch and ulnar loop types than the right handers and less whorl and radial loop types than the right handers. In the left hand, the 3rd (p<0.05), 4th (p<0.05), and 5th (p<0.01) fingerprints of the left handers were different from those of the right handers. The finger ridge counts of left handers were significantly less than those of the right handers in the 2nd and 3rd fingers of the left hand, and in the 3rd and 4th fingers in the right hand. The triradii counts of left handers were significantly less than those of right handers (p<0.05) in the 3rd, 4th, and 5th finger of the left and right hand. Total triradii counts of left handers were also significantly less than those of right handers (p<0.05). These results demonstrate that fingerprint type, finger ridge and triradius counts of the left handers are different from those of the right handers, and fingerprints may reflect genetic tendency for handedness.

BACKGROUND: Although scalp whorls and the anterior hairline are important parts for the morphology of the scalp hair pattern, only a few studies on them have been reported. OBJECTIVE: This study was performed to obtain data about the classification and incidence of various scalp whorl patterns, the average heights of the anterior hairlines, and the types of anterior hairlines and their incidence. METHOD: We evaluated the number, direction and location of the parietal scalp whorls, measured the heights of the frontal and temporal hairlines according to the 5 standard lines, and identified the shape of the anterior hairlines in 484 men and 171 women. RESULTS: Of the 655 subjects, 89.6% had single parietal scalp whorls, while 6.9% had double whorls. The single clockwise type was more common than the single counterclockwise types, and the location of single whorls were in the middle, right and left, in decreasing order of frequency. Of the double whorls, cases of the same direction were more common than those of opposite directions. The average height of the anterior hairline was higher in men than women. For the classification of the anterior hairline, the linear type was the most common in men and the round type more common in women. CONCLUSION: We describe the present results as a guideline for the further study of hair-related abnormalities and also for the esthetic design of hair transplantations.
