Mehra, U.R.,Verma, A.K.,Dass, R.S. Asian Australasian Association of Animal Productio 1998 Animal Bioscience Vol.11 No.1

To compare response of feeding concentrate mixtere and wheat straw (Group I) with either urea molasses liquid diet (UMLD) as sole ration (group II) or UMLD (similar to protein equivalent of concentrate mixture) plus wheat straw (group III) on intake and utilisation of nutrients and overall performance, twelve crossbred adult male cattle (Holstein Friesian ${\times}$ Hariana) aged about 2.5 years and weighing 342 kg were randomly allotted into three equal groups following completely randomised design and fed respective diets for a period of 60 days. Thereafter, a metabolism trial of seven days duration was conducted to assess nutrient utilisation and nitrogen balance. Animals fed UMLD as sole ration consumed significantly (p < 0.01) less amount of most of the nutrients as compared to other two groups, except crude protein, intake of which was higher in this group but it was comparable between II and III and III and I. On the other hand, digestibilities of nutrients were higher (p < 0.01) in group II, though it was comparable between other two groups, except ADF, the digestibility of which was lower in group II. Inspite of positive nitrogen balance in all the three groups, being significantly (p < 0.01) higher in group I, animals of group II and III lost their body weight especially to the utmost extent in group II, although the amount of energy (TDN) intake were similar statistically. Results indicate that during a scarcity period and economic compulsions, feeding of UMLD can be practised to replace only concentrate mixture from the maintenance ration of adult crossbred cattle for shorter duration as roughage part seems to be essential for the normal functioning of the rumen microbes and overall performance of the animals.

Mehra, Navita,Mittal, Pooja International Journal of Computer ScienceNetwork S 2022 International journal of computer science and netw Vol.22 No.7

The current progression in the Internet of Things (IoT) and Machine Learning (ML) based technologies converted the traditional healthcare system into a smart healthcare system. The incorporation of IoT and ML has changed the way of treating patients and offers lots of opportunities in the healthcare domain. In this view, this research article presents a new IoT and ML-based disease diagnosis model for the diagnosis of different diseases. In the proposed model, vital signs are collected via IoT-based smart medical devices, and the analysis is done by using different data mining techniques for detecting the possibility of risk in people's health status. Recommendations are made based on the results generated by different data mining techniques, for high-risk patients, an emergency alert will be generated to healthcare service providers and family members. Implementation of this model is done on Anaconda Jupyter notebook by using different Python libraries in it. The result states that among all data mining techniques, SVM achieved the highest accuracy of 0.897 on the same dataset for classification of Parkinson's disease.

Mehra, Archana,Karjodkar, Freny R.,Sansare, Kaustubh,Kapoor, Ruchika,Tambawala, Shahnaz,Saxena, Vasu Siddhartha Korean Academy of Oral and Maxillofacial Radiology 2021 Imaging Science in Dentistry Vol.51 No.1

Purpose: This study was conducted to establish age- and sex-specific reference standards for pterygoid hamulus(PH) dimensions using cone-beam computed tomography (CBCT). Materials and Methods: CBCT scans of 1,000 patients(493 males and 507 females) were retrospectively assessed in coronal sections for length and width measurements of the PH by 3 investigators. The study data were divided into 3 age groups(group 1: <20 years, group 2: 20-50 years, group 3: >50 years). Length and width were compared using one-way analysis of variance and the t-test for age and sex, respectively. Results: The length of the PH on the right side significantly increased from group 1 (6.11±1.47mm), through group 2 (6.65±1.67 mm) to group 3 (6.99±1.79 mm) and on the left side from group 2 (6.58±1.63) to group 3 (6.98±1.70). The width of the PH significantly decreased from group 1 (1.81±0.39 mm) to group 2 (1.61±0.39 mm) on the right side, and similarly from 1.87±0.36mm to 1.67±0.37mm on the left side. PH length (7.18±1.81mm on the right side and 7.10±1.72 mm on the left side) and width (1.68±0.38 mm on the right side and 1.74±0.36 mm on the left side) were significantly greater in males than in females. Conclusion: The length of the PH increased with age, whereas width first decreased and then increased. Length and width measurements were significantly higher in males than in females. These findings will aid in the diagnosis of untraceable pain in the oropharyngeal region related to altered PH morphology.

Effect of Feeding Urea and Acetic Acid Treated Wheat Straw on the Digestibility of Nutrients in Adult Male Murrah Buffaloes (Bubalus bubalis)

Mehra, Usha R.,Dass, R.S.,Verma, A.K.,Sahu, D.S. Asian Australasian Association of Animal Productio 2001 Animal Bioscience Vol.14 No.12

Wheat straw was treated on laboratory scale with 4% urea at a moisture level of 50% along with different amounts of acetic acid (AA) to fix various levels of ammonia nitrogen (15, 30, 45 and 60%) evolved from urea and stored for 4 weeks. Chemical composition of the treated samples revealed a significant (p<0.01) increase in N content of the samples where AA was added. The N content of the ammoniated straw was only 1.21% which increased to 2.58 with the addition of AA to trap 30% $NH_3-N$. The concentration of free $NH_3-N$ in the straw was significantly (p<0.01) less when more than 15% $NH_3-N$ was trapped with AA. There was significant increase (p<0.01) in N disappearance and depression in NDF and hemicellulose disappearance, when AA was used to trap 30% $NH_3-N$. Large scale treatment of wheat straw with 4% urea at a moisture level of 50% along with AA (to trap 30% $NH_3-N$) increased the N content, but not as much as in laboratory scale treatment. In vivo experiment conducted on nine adult male buffaloes divided into three groups revealed no difference in the intake of DM, OM, NDF, ADF, cellulose and hemicellulose among group I (ammoniated straw), group II (AA treated ammoniated straw) and group III (AA treated ammoniated straw +1 kg barley grain), but the intake was significantly (p<0.05) more in groups where AA treated straw was fed as compared to only ammoniated straw fed group. However EE digestibility was depressed in group II. The digestibility of cellulose and hemicellulose both depressed significantly (p<0.05) in group II and III as compared to group I. Animals in all the 3 groups showed positive nitrogen balance and it was significantly more in group II and III as compared to group I. DCP intake was significantly (p<0.05) more in group II and III as compared to group I, but there was no significant difference among the three groups in TDN intake. It can be concluded that AA (to trap 30% $NH_3-N$) is effective in capturing the excess ammonia released during urea ammoniation of straw and improving its nutritive value, as well as animal performance.

Mehra, U.R.,Khan, M.Y.,Lal, Murari,Hasan, Q.Z.,Das, Asit,Bhar, R.,Verma, A.K.,Dass, R.S.,Singh, P. Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.5

Sixteen adult male buffaloes (average body weight $443{\pm}14kg$) were equally distributed into four groups in an experiment to study the effect of supplementary protein sources on energy utilization efficiency in buffaloes fed a wheat straw-based diet. The animals in the control group were offered a basal diet composed of 700 g deoiled ground nut cake and ad libitum wheat straw. Animals of other groups were offered 1.8 kg of soyabean meal (SBM), linseed meal (LSM) or mustard cake (MC) along with the basal diet. Protein supplementation increased the digestibility of DM (p<0.01), OM (p<0.01) CP (p<0.01) and CF (p<0.05). Maximum CP digestibility was observed on SBM, followed by LSM and MC when compared to the control. Total DMI and DOMI was significantly (p<0.01) higher in protein supplemented groups with no differences between treatment groups. Digestible crude protein (DCP) intake and N balance were significantly (p<0.01) different between the groups; maximum response was obtained with SBM supplementation, followed by LSM and MC. Faecal energy was significantly (p<0.01) lower in SBM and LSM groups in comparison to other groups. Methane production (% DEI) was significantly (p<0.05) lower on the SBM treatment. Metabolizable energy (ME) intake increased significantly due to protein supplementation. Metabolizable energy intake (MEI) of animals in the MC group was less than LSM and SBM. Energy balance was increased significantly (p<0.01) due to protein supplementation and within supplement variation was also significant with maximum balance in SBM followed by LSM and MC groups. Protein supplementation significantly (p<0.05) increased the digestibility and metabolizability of energy from whole ration. Metabolizable energy (ME) content (Mcal/kg DM) of SBM, LSM and MC was 4.49, 3.56 and 2.56, respectively. It was concluded that protein supplementation of wheat straw increased intake, digestibility and metabolizability of energy and maximum response could be obtained when soybean meal was used as a supplement.

Sidhu, Mehra S.,Choi, Min-Yeong,Woo, Suk-Yi,Lee, Hyun-Kyu,Lee, Heung-Soon,Kim, Kyu-Jin,Jeoung, Sae Chae,Choi, Jun-Sub,Joo, Choun-Ki,Park, Il-Hong Springer London 2014 LASERS IN MEDICAL SCIENCE Vol.29 No.4

<P>Nonlinear multiphoton absorption induced by focusing near infrared (NIR) femtosecond (fs) laser pulses into a transparent cornea allows surgery on neovascular structures with minimal collateral damage. In this report, we introduce an fs laser-based microsurgery for selective treatment of rat corneal neovascularizations (in vivo). Contiguous tissue effects are achieved by scanning a focused laser pulse below the corneal surface with a fluence range of 2.2–8.6 J/cm<SUP>2</SUP>. The minimal visible laser lesion (MVL) threshold determined over the corneal neovascular structures was found to be 4.3 J/cm<SUP>2</SUP>. Histological and optical coherence tomography examinations of the anterior segment after laser irradiations show localized degeneration of neovascular structures without any unexpected change in adjacent tissues. Furthermore, an approximately 30 % reduction in corneal neovascularizations was observed after 5 days of fs laser exposure. The femtosecond laser is thus a promising tool for minimally invasive intrastromal surgery with the aid of a significantly smaller and more deterministic photodisruptive energy threshold for the interaction between the fs laser pulse and corneal neovascular structures.</P>

Dorsoscapularis triangularis: embryological and phylogenetic characterization of a rare variation of trapezius

Lalit Mehra,Anita Tuli,Shashi Raheja 대한해부학회 2016 Anatomy & Cell Biology Vol.49 No.3

The muscle trapezius shows considerable morphological diversity. Variations include an anomalous origin and complete or partial absence of the muscle. The present study reported, a hitherto undocumented complete bilateral absence of the cervical part of trapezius. Based on its peculiar origin and insertion, it was named dorsoscapularis triangularis. The embryological, phylogenetic and molecular basis of the anomaly was elucidated. Failure of cranial migration of the trapezius component of the branchial musculature anlage to gain attachment on the occipital bone, cervical spinous processes, ligamentum nuchae between 11 mm and 16 mm stage of the embryo, resulted in this anomaly. A surgeon operating on the head and neck region or a radiologist analyzing a magnetic resonance imaging of the cervical region would find the knowledge of this morphological variation of trapezius useful in making clinical decisions.

Prospective comparison of suture ligation and electrothermal sealing for the control of perivascular lymphatics in kidney transplant recipients

Ketan Mehra,Kushal Kapashi,Sajni Khemchandani,Pranjal Ramanlal Modi,Syed Jamal Rizvi 대한이식학회 2022 Korean Journal of Transplantation Vol.36 No.4

Background: The use of sutures as ligatures has proven to be safe and reliable for the control of lymphatic vessels. The electrothermal bipolar vessel sealer (EBVS) is a relatively new type of device that can be used to seal lymphatics. We conducted a study to evaluate the safety and efficacy of EBVS for preparation of the recipient vessel during renal transplantation. Methods: In this prospective randomized controlled study, EBVS (Medtronic) was compared with conventional ligature for the control of perivascular lymphatics in kidney transplant recipients. A total of 52 kidney transplant recipients were randomly assigned to two groups. In group 1, EBVS was used to control perivascular lymphatics, while conventional silk ligatures were used in group 2. Demographic characteristics, as well as preoperative, perioperative, and postoperative variables, were noted and compared between the groups. Results: The mean recipient vessel preparation time was 8.3±1.9 minutes in group 1 and 14.5±4 minutes in group 2 (P<0.001). The mean anastomosis time was 28.2±5.4 minutes in group 1 and 28.2±4.2 minutes in group 2 (P=1.000). The mean estimated blood loss was 101.54±44.60 mL in group 1 and 125.19±74.17 mL in group 2 (P=0.270), and the mean drain output was 51.42 mL per day and 57.50 mL per day in groups 1 and 2, respectively (P=0.590). Conclusions: EBVS can be employed safely and effectively for recipient iliac lymphatic vessel dissection and sealing. EBVS is a fast, secure, and effective choice to permanently fuse the vessels and is a good option to avoid posttransplant lymphatic complications.

Simmi Mehra,Neetu Tyagi,Pranav Dorwal,Amit Pande,Dharmendra Jain,Ritesh Sachdev,Vimarsh Raina 대한혈액학회 2015 Blood Research Vol.50 No.2

BackgroundThe eosin-5'-maleimide (EMA) binding test using flow cytometry is a common methodto measure reduced mean channel fluorescence (MCF) of EMA-labeled red blood cells(RBCs) from patients with red cell membrane disorders. The basic principle of theEMA-RBC binding test involves the covalent binding of EMA to lysine-430 on the first extracellularloop of band 3 protein. MethodsIn the present study, the MCF of EMA was analyzed for samples derived from 12 healthyvolunteers (controls) to determine the stability (i.e., the percentage decrease in fluorescence)of EMA over a period of 1 year. ResultsComparison of periodical MCF readings over time, that is, at 2-month intervals, showedthat there were no significant changes in mean channel fluorescence for up to 6 months;however, there was a significant decrease in MCF at 8 months. ConclusionFor optimal dye utilization, EMA remained stable only for up to 6 months. Therefore, werecommend reconstitution of the dye every 6 months when implementing this test andstorage at -80oC in dark conditions.

ORiginal Article : Sonographic Evaluation of Gallbladder Motility in Children with Chronic Functional Constipation

( Rakesh Mehra ),( Kushaljit Singh Sodhi ),( Akshay Saxena ),( Br Thapa ),( Niranjan Khandelwal ) The Editorial Office of Gut and Liver 2015 Gut and Liver Vol.9 No.3

Background/Aims: Studies in adults suggest that constipation may not be a purely colonic pathology and may be a component of a generalized gastrointestinal (GI) motor disorder in which proximal GI motility can be impaired. Pediatric data are scarce, and the natural history of the disorder remains undefined. We aimed to evaluate gallbladder motility in a subset of Asian children with chronic functional constipation. Methods: Abdominal ultrasound was performed on 105 children, including 55 patients (aged 3 to 13 years) with chronic functional constipation who met the inclusion criteria and 50 age- and gender-matched controls. The gallbladder contractility index was calculated based on the preprandial and postprandial gallbladder areas. Preprandial and postprandial values for gallbladder volume and wall thickness were evaluated. Results: The mean value of the contractility index for the patients (15.77±24.68) was significantly lower than the mean value for the controls (43.66±11.58) (p=0.001). The mean postprandial gallbladder volumes and areas were larger in children with gallbladder hypomotility (p<0.05). The mean duration of constipation (4.8 months) was significantly higher (p=0.004) in the children with gallbladder hypomotility. Conclusions: Gallbladder motility is significantly impaired in children with chronic functional constipation. This study contributes to the understanding of the underlying pathophysiology, which will enable advancement in and improved management of children with chronic constipation and associated gallbladder hypomotility.
