Usporedba lidokaina i kombinacije lidokaina i ketamina primijenjenih za distalnu intravensku regionalnu anesteziju (DIVRA) u goveda
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 lijeÄiti pod intravenskom regionalnom anestezijom (IVRA). Za rutinsko uvoÄenje u IVRA-u postavlja se kružno Ävrsti zavoj na metakarpus/metatarzus. U ovom su istraživanju bolesti papaka u goveda lijeÄene modificiranom IVRA metodom. Istražene životinje nasumiÄno 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 uvoÄenje u distalnu intravensku regionalnu anesteziju (DIVRA) anestetici su aplicirani u aksijalnu digitalnu venu. SrÄana frekvencija, frekvencija disanja, sistoliÄki i dijastoliÄki tlak u obje su skupine bili nepromijenjeni. ZasiÄenost kisikom bila je znakovito niža (P<0,05) izmeÄu 5. i 60. minute u skupini I te izmeÄu 15. i 40. minute u skupini II. Vrijeme pojave senzornih i motoriÄkih blokova bilo je kraÄe, a vrijeme oporavka tih blokova dulje u životinja u skupini II u usporedbi sa skupinom I. ZakljuÄeno 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
ANALOGY OF MODERN CHEMICAL PROCESSES WITH PRINCIPLES OF āRASA SHASTRA' OF AYURVEDIC MEDICINE SYSTEM
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, āRasayanā (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
RASAYANA: THE REJUVENATING REMEDY FOR HEALTH
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 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 gravity model in
vacuum. We analyse the action with a small positive deviation from the
Einstein-Hilbert action (taking as ) at the
galactic scales for the explanation of cosmological dark matter problem and
obtain the contribution of dynamical 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
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
background for the model parameter and interpret the results
for its satellite galaxies.Comment: 7 pages, 5 figure
Light deflection angle through velocity profile of galaxies in model
We explore a new realisation of the galactic scale dynamics via gravitational
lensing phenomenon in power-law gravity theory of the type with for interpreting the clustered dark matter
effects. We utilize the single effective point like potential (Newtonian
potential + 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 frame work. We calculate the
magnitude of light deflection angle with the characteristic length scale
(because of Noether symmetry in theories) appearing in the effective
rotational velocity profile of a typical galaxy with the model parameter
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
background. We also contrast the magnitudes of 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
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
Evaluation of association of vitamin D level with types of proximal femoral fractures in elderly patients
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 >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
Aedes aegypti lachesin protein binds to the domain III of envelop protein of Dengue virus-2 and inhibits viral replication.
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
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
