    The hoof diseases of cattle can be managed surgically under intravenous regional anesthesia (IVRA). For routine induction of IVRA, a tourniquet is placed circumferentially at the metacarpus/metatarsus. In the present study, hoof diseases of cattle were corrected using a modified IVRA technique. The cattle with hoof ailments were randomly divided into two groups and a tourniquet was placed just distal to the dew claws instead of at the metacarpus/metatarsus in order to decrease the dose of anesthetic. In group I lidocaine (2mg/kg) and in group II a mixture of lidocaine and ketamine (2mg/kg+1.5mg/kg) was injected into the axial digital vein to induce distal intravenous regional anesthesia (DIVRA). The heart rate, respiration rate, systolic and diastolic pressure were unaffected in both groups. Oxygen saturation was significantly (P<0.05) lower between 5 and 60 minutes in group I and between 15 and 40 minutes in group II animals. The sensory and motor block onset time was shorter, and the sensory and motor block recovery time was longer in group II animals as compared to group I animals. It was concluded that the DIVRA technique using lidocaine alone and lidocaine admixed with ketamine are suitable for hoof examination and surgery.Bolesti papaka u goveda mogu se kirurÅ”ki liječiti pod intravenskom regionalnom anestezijom (IVRA). Za rutinsko uvođenje u IVRA-u postavlja se kružno čvrsti zavoj na metakarpus/metatarzus. U ovom su istraživanju bolesti papaka u goveda liječene modificiranom IVRA metodom. Istražene životinje nasumično su podijeljene u dvije skupine a zavoj kojim se samnjuje doza anestetika postavljen je, umjesto na metakarpus/metatarzus, distalno od rudimentiranih papaka. U skupini I primijenjen je lidokain (2 mg/kg), a u skupini II kombinacija lidokaina i ketamina (2 mg/kg + 1,5 mg/kg). Za uvođenje u distalnu intravensku regionalnu anesteziju (DIVRA) anestetici su aplicirani u aksijalnu digitalnu venu. Srčana frekvencija, frekvencija disanja, sistolički i dijastolički tlak u obje su skupine bili nepromijenjeni. Zasićenost kisikom bila je znakovito niža (P<0,05) između 5. i 60. minute u skupini I te između 15. i 40. minute u skupini II. Vrijeme pojave senzornih i motoričkih blokova bilo je kraće, a vrijeme oporavka tih blokova dulje u životinja u skupini II u usporedbi sa skupinom I. Zaključeno je da je DIVRA, uz upotrebu i samog lidokaina i lidokaina u kombinaciji s ketaminom, prikladna metoda za pregled i obavljanje kiruÅ”kih zahvata na papcima goveda

    Ayurveda is basically a medical science but different branches of science were nurtured by it like biology, genetics, microbiology, clinical medicine, surgery, astronomy, pharmaceutics and metallurgy etc. In this traditional therapeutic system, various categories of formulations have been described in official and traditional literature. Similar to modern system of therapeutics, various units operations were adopted in developing various dosage forms to obtain the desired effect upto the optimum time. Every step has been explained in detail in traditional literature and sight modifications have also been mentioned in some texts. Besides these, numbers of metals, their alloys, metallurgy etc. have also been elaborated for the well being of the society. Hitherto, ā€˜Rasayanā€™ (chemistry) and the associated studies were also familiar in ancient time. Various chemical like common salt, alkali, borax and compounds of elements like Fe, Cu, Hg and Au etc., were commonly used from in that period and the techniques for making alloys of bronze, brass, and bell metal etc. were also very common. The applicability of natural preservatives like oil, salt and sugar were also much known in ancient time. However; the terms used as stated in traditional literature were not similar to modern time. Also, the alcoholic and acidic fermented products were prepared very commonly. The present study has been focused to assess the similarity of chemical terms mentioned in literature with modern science and technology

    Gradual increase of Population in urban area may leads to environmental pollution and microbial infection in air and water increases exponentially. Most of the persons in the population are in trap of mental stress and depression due to struggle in the life and overload of work. So both of these conditions are responsible for so many disease and ill-health, and one more important thing is that due to increase negligence and uninhabited use of processed food, the ill effects on health are compound manifold when coupled with unhealthy lifestyle and food habits. So there is a need of taking dietary supplementary food or nutraceutical. The main aim of Ayurveda has been working upon a twofold process i.e., to maintain the health of a healthy individual and to treat the one with the disease. Thus by laying emphasis on the first aspect and combining it with the knowledge of the role of phytochemical as, one can gradually deduce an effective module for living healthy and line of treatment of metabolic and geriatric disorders. The phytochemical are the essential nutrients, which are naturally contained in plants and are required for normalĀ physiological functions. The Rasayan not only boost general health but also provide the necessary raw materials to strengthen the defense mechanism of the body.

    Extended galactic rotational velocity profiles in f(R)f(R) gravity background

    An attempt has been made to explore the galactic dynamics via the rotational velocity beyond the Einstein's geometric theory of gravity. It is inspired from the geometric relation obtained in the power law f(R)f(R) gravity model in vacuum. We analyse the action with a small positive deviation from the Einstein-Hilbert action (taking RR as f(R)āˆR1+Ī“f(R)\propto R^{1+\delta}) at the galactic scales for the explanation of cosmological dark matter problem and obtain the contribution of dynamical f(R)f(R) background geometry in accelerating the test mass. In the weak field limits, we obtain the effective acceleration of the test mass due to a massive spherically symmetric source in f(R)f(R) background and develop an equation for the rotational velocity. We test the viability of the model by tracing the motion of test mass outside the typical galactic visible boundaries without considering any dark matter halo profile. We obtain a nice agreement in the outer regions (up to few tens of kpc beyond the visible boundary) of the typical galaxy by using the known galaxy data.\\ We further explore the galactic dynamics for a galaxy NGC 1052 of which the dark matter deficient galaxies, i.e., DF2 and DF4 are a part (satellite galaxies) and discuss plots of the dynamical feature of rotation curves in f(R)f(R) background for the model parameter Ī“<<1\delta<<1 and interpret the results for its satellite galaxies.Comment: 7 pages, 5 figure

    Light deflection angle through velocity profile of galaxies in f(R)f(R) model

    We explore a new realisation of the galactic scale dynamics via gravitational lensing phenomenon in power-law f(R)f(R) gravity theory of the type f(R)āˆR1+Ī“f(R)\propto R^{1+\delta} with Ī“<<1\delta<<1 for interpreting the clustered dark matter effects. We utilize the single effective point like potential (Newtonian potential + f(R)f(R) background potential) obtained under the weak field limit to study the combined observations of galaxy rotation curve beyond the optical disk size and their lensing profile in f(R)f(R) frame work. We calculate the magnitude of light deflection angle with the characteristic length scale (because of Noether symmetry in f(R)f(R) theories) appearing in the effective f(R)f(R) rotational velocity profile of a typical galaxy with the model parameter Ī“ā‰ˆO(10āˆ’6)\delta \approx O(10^{-6}) constrained in previous work. For instance, we work with the two nearby controversial galaxies NGC 5533 and NGC 4138 and explore their galactic features by analysing the lensing angle profiles in f(R)f(R) background. We also contrast the magnitudes of f(R)f(R) lensing angle profiles and the relevant parameters of such galaxies with the generalised pseudo-isothermal galaxy halo model and find consistency.Comment: 7 pages, 5 figure

    Quantification of Pollen Viability in Lantana camara By Digital Holographic Microscopy

    Full text link
    Pollen grains represent the male gametes of seed plants and their viability is critical for efficient sexual reproduction in the plant life cycle. Pollen analysis is used in diverse research thematics to address a range of botanical, ecological and geological questions. More recently it has been recognized that pollen may also be a vector for transgene escape from genetically modified crops, and the importance of pollen viability in invasion biology has also been emphasized. In this work, we analyse and report an efficient visual method for assessing the viability of pollen using digital holographic microscopy (DHM). We test this method on pollen grains of the invasive Lantana camara, a well known plant invader known to most of the tropical world. We image pollen grains and show that the quantitative phase information provided by the DHM technique can be readily related to the chromatin content of the individual cells and thereby to pollen viability. Our results offer a new technique for pollen viability assessment that does not require staining, and can be applied to a number of emerging areas in plant science.Comment: 13 pages, 5 figure

    Background: Proximal femoral fractures are very common in elderly patients. These fractures are thought to be associated with osteoporosis. Vitamin D is a possible risk factor for osteoporosis. So, this study was done to evaluate the association of serum vitamin D level with types of femoral fractures in elderly patients.Methods: The study was done between September 2013 to August 2016, 75 patients with age &gt;60 years (male and female both) with proximal femoral fractures were studied. Serum 25-hydroxy vitamin D, calcium, phosphate, alkaline phosphatase levels, liver function test, renal function test, hemoglobin and complete blood counts of all the patients were assessed.Results: On assessment of serum vitamin D in proximal femoral fracture in elderly patients, it shows an increase incidence of proximal femoral fractures in patients with low serum vitamin D level. Fracture of neck of femur was most common among all. Type of fracture has no significant statistical relationship with serum vitamin D levels.Conclusions: Osteoporosis and serum vitamin D level depends on age and sex of the patient. But type of proximal femoral osteoporotic fracture has no association with either grade of osteoporosis or serum vitamin D level

    Dengue virus (DENV) comprises of four serotypes (DENV-1 to -4) and is medically one of the most important arboviruses (arthropod-borne virus). DENV infection is a major human health burden and is transmitted between humans by the insect vector, Aedes aegypti. Ae. aegypti ingests DENV while feeding on infected humans, which traverses through its gut, haemolymph and salivary glands of the mosquito before being injected into a healthy human. During this process of transmission, DENV must interact with many proteins of the insect vector, which are important for its successful transmission. Our study focused on the identification and characterisation of interacting protein partners in Ae. aegypti to DENV. Since domain III (DIII) of envelope protein (E) is exposed on the virion surface and is involved in virus entry into various cells, we performed phage display library screening against domain III of the envelope protein (EDIII) of DENV-2. A peptide sequence showing similarity to lachesin protein was found interacting with EDIII. The lachesin protein was cloned, heterologously expressed, purified and used for in vitro interaction studies. Lachesin protein interacted with EDIII and also with DENV. Further, lachesin protein was localised in neuronal cells of different organs of Ae. aegypti by confocal microscopy. Blocking of lachesin protein in Ae. aegypti with anti-lachesin antibody resulted in a significant reduction in DENV replication

    Fresnel zone plate telescopes for X-ray imaging II: numerical simulations with parallel and diverging beams

    Full text link
    We present the results of simulations of shadows cast by a zone plate telescope which may have one to four pairs of zone plates. From the shadows we reconstruct the images under various circumstances. We discuss physical basis of the resolution of the telescope and demonstrate this by our simulations. We allow the source to be at a finite distance (diverging beam) as well as at an infinite distance (parallel beam) and show that the resolution is worsened when the source is nearby. By reconstructing the zone plates in a way that both the zone plates subtend the same solid angles at the source, we obtain back high resolution even for sources at a finite distance. We present simulated results for the observation of the galactic center and show that the sources of varying intensities may be reconstructed with accuracy. Results of these simulations would be of immense use in interpreting the X-ray images from recently launched CORONAS-PHOTON satellite.Comment: 17 pages, 36 figures, Published in Experimental Astronom
