A Critical Review on Go-Ghrita, Shata Dhouta Ghrita and Sahasra Dhouta Ghrita
Traditional medical system has always played an important role in the maintenance of health of mankind. Modern medicine has been drawing inputs from these traditional systems since their very beginning. Samskara in Ayurveda, is a process of transformation of inherent attributes of a substance. This is created by dilution, application of heat, cleansing, churning, storing in a specific place, maturing, flavoring, impregnation, preservation, container etc. Ancient scholars considered that Ghrita is able to perform multiple actions if processed accordingly. On the base of this, many Samskaras are employed for Ghrita and subsequently various pharmacological actions are observed. Shatadhouta Ghrita and Sahsradhouta Ghrita are also an outcome of that keen observation. Shatadhouta Ghrita and Sahasradhouta Ghrita are two Ayurvedic preparations, which are prepared by washing cow ghee for hundred and thousand times respectively. They are considered as best alleviators of Pitta Dosha and burning sensation, in the treatments of wound healing. On the basis of detailed literary review, it was understood that, Shatadhouta Ghrita and Sahasradhouta Ghrita should be prepared by pressure washing of Ghrita with water. These preparations are indicated for Dahashamana action. Both of them have the properties as that of oil in water kind of emulsion
Cellular dissection of psoriasis for transcriptome analyses and the post-GWAS era
Abstract
Background
Genome-scale studies of psoriasis have been used to identify genes of potential relevance to disease mechanisms. For many identified genes, however, the cell type mediating disease activity is uncertain, which has limited our ability to design gene functional studies based on genomic findings.
Methods
We identified differentially expressed genes (DEGs) with altered expression in psoriasis lesions (n = 216 patients), as well as candidate genes near susceptibility loci from psoriasis GWAS studies. These gene sets were characterized based upon their expression across 10 cell types present in psoriasis lesions. Susceptibility-associated variation at intergenic (non-coding) loci was evaluated to identify sites of allele-specific transcription factor binding.
Results
Half of DEGs showed highest expression in skin cells, although the dominant cell type differed between psoriasis-increased DEGs (keratinocytes, 35%) and psoriasis-decreased DEGs (fibroblasts, 33%). In contrast, psoriasis GWAS candidates tended to have highest expression in immune cells (71%), with a significant fraction showing maximal expression in neutrophils (24%, P < 0.001). By identifying candidate cell types for genes near susceptibility loci, we could identify and prioritize SNPs at which susceptibility variants are predicted to influence transcription factor binding. This led to the identification of potentially causal (non-coding) SNPs for which susceptibility variants influence binding of AP-1, NF-κB, IRF1, STAT3 and STAT4.
Conclusions
These findings underscore the role of innate immunity in psoriasis and highlight neutrophils as a cell type linked with pathogenetic mechanisms. Assignment of candidate cell types to genes emerging from GWAS studies provides a first step towards functional analysis, and we have proposed an approach for generating hypotheses to explain GWAS hits at intergenic loci.http://deepblue.lib.umich.edu/bitstream/2027.42/109537/1/12920_2013_Article_485.pd
Patellofemoral pain syndrome (PFPS): a systematic review of anatomy and potential risk factors
Patellofemoral Pain Syndrome (PFPS), a common cause of anterior knee pain, is successfully treated in over 2/3 of patients through rehabilitation protocols designed to reduce pain and return function to the individual. Applying preventive medicine strategies, the majority of cases of PFPS may be avoided if a pre-diagnosis can be made by clinician or certified athletic trainer testing the current researched potential risk factors during a Preparticipation Screening Evaluation (PPSE). We provide a detailed and comprehensive review of the soft tissue, arterial system, and innervation to the patellofemoral joint in order to supply the clinician with the knowledge required to assess the anatomy and make recommendations to patients identified as potentially at risk. The purpose of this article is to review knee anatomy and the literature regarding potential risk factors associated with patellofemoral pain syndrome and prehabilitation strategies. A comprehensive review of knee anatomy will present the relationships of arterial collateralization, innervations, and soft tissue alignment to the possible multifactoral mechanism involved in PFPS, while attempting to advocate future use of different treatments aimed at non-soft tissue causes of PFPS
The Zinc Dyshomeostasis Hypothesis of Alzheimer's Disease
Alzheimer's disease (AD) is the most common form of dementia in the elderly. Hallmark AD neuropathology includes extracellular amyloid plaques composed largely of the amyloid-β protein (Aβ), intracellular neurofibrillary tangles (NFTs) composed of hyper-phosphorylated microtubule-associated protein tau (MAP-tau), and microtubule destabilization. Early-onset autosomal dominant AD genes are associated with excessive Aβ accumulation, however cognitive impairment best correlates with NFTs and disrupted microtubules. The mechanisms linking Aβ and NFT pathologies in AD are unknown. Here, we propose that sequestration of zinc by Aβ-amyloid deposits (Aβ oligomers and plaques) not only drives Aβ aggregation, but also disrupts zinc homeostasis in zinc-enriched brain regions important for memory and vulnerable to AD pathology, resulting in intra-neuronal zinc levels, which are either too low, or excessively high. To evaluate this hypothesis, we 1) used molecular modeling of zinc binding to the microtubule component protein tubulin, identifying specific, high-affinity zinc binding sites that influence side-to-side tubulin interaction, the sensitive link in microtubule polymerization and stability. We also 2) performed kinetic modeling showing zinc distribution in extra-neuronal Aβ deposits can reduce intra-neuronal zinc binding to microtubules, destabilizing microtubules. Finally, we 3) used metallomic imaging mass spectrometry (MIMS) to show anatomically-localized and age-dependent zinc dyshomeostasis in specific brain regions of Tg2576 transgenic, mice, a model for AD. We found excess zinc in brain regions associated with memory processing and NFT pathology. Overall, we present a theoretical framework and support for a new theory of AD linking extra-neuronal Aβ amyloid to intra-neuronal NFTs and cognitive dysfunction. The connection, we propose, is based on β-amyloid-induced alterations in zinc ion concentration inside neurons affecting stability of polymerized microtubules, their binding to MAP-tau, and molecular dynamics involved in cognition. Further, our theory supports novel AD therapeutic strategies targeting intra-neuronal zinc homeostasis and microtubule dynamics to prevent neurodegeneration and cognitive decline
Lawson criterion for ignition exceeded in an inertial fusion experiment
For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37Â MJ of fusion for 1.92Â MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion

Not AvailableChronic suppurative lymphadenitis characterized by abscess formation is of economic significance in sheep and
goats. It is principally caused by Corynebacterium pseudotuberculosis (caseous lymphadenitis, CLA) and Staphylococcus
aureus subsp. anaerobius. Pus samples from superficial lymph nodes of 33 (4.38 %) out of 752 adult Sirohi goats showing
clinical lesions similar to CLA were collected for laboratory investigations. Sixteen (48.48 %) bacterial isolates from pus
were identified as C. pseudotuberculosis, 12 (36.36 %) as catalase-negative S. aureus subsp. anaerobius while samples
from 5 cases were negative. The polymerase chain reaction (PCR) assays targeting putative oligopeptide/dipeptide ABC
transporter, nicotinamide adenine dinucleotide phosphate oxidoreductase coenzyme F420-dependent and proline
iminopeptidase genes of C. pseudotuberculosis when carried out directly on the DNA extracted from pus were positive in
the same 16 goats. All the C. pseudotuberculosis isolates were also found to be positive for these genes in the PCR. Isolates
of S. aureus subsp. anaerobius were found to be positive for 16S rRNA and nuclease (nuc) gene PCR. The present study
shows the incidence of CLA as 4.38, 2.12 and 2.12 % based on the clinical, bacterial culture and direct PCR assay on pus
samples, respectively. The incidence of abscess disease due to S. aureus subsp. anaerobius was 1.59 %. The three gene
PCR assay developed in the study was found to be specific and rapid than the bacterial culture in detecting bacteria directly
in the pus samples and can be applied for the diagnosis and control strategy of CLA.Not Availabl
