Raspodjele složene višestrukosti u sudarima jezgra-jezgra – proučavanje faznog prijelaza

Experimental data on compound multiplicity distribution produced in 24Mg-AgBr and 12C-AgBr interactions, both at 4.5A GeV, have been analysed in terms of scaled factorial moments. We have calculated the values of generalized dimension Dq for q = 2, 3, 4, 5, 6 and 7 with the help of intermittency exponent αq. From the knowledge of Dq, the multifractal specific heat is calculated for different multiplicity bin ranges. The parameter λq (λq = (αq + 1)/q) is calculated from αq to look for possible non-thermal phase transition. The analysis reveals no evidence of nonthermal phase transition. Instead, different specific heat in different multiplicity bins has been observed.Analizirali smo eksperimentalne podatke o raspodjelama složene višestrukosti u sudarima 24Mg-AgBr i 12C-AgBr, oba na 4.5A GeV, primjenom prilagodnih faktorijalnih momenata. Izračunali smo vrijednosti poopćene dimenzije Dq za q = 2, 3, 4, 5, 6 i 7 pomoću eksponenta prekidanja αq. Te vrijednosti Dq primijenili smo za izračunavanje višefraktalne specifične topline za niz pretinaca. Parametar λq (λq = (αq + 1)/q) smo izračunali na osnovi αq tražeći netermički fazni prijelaz. Analiza nije pokazala prisutnost netermičkog faznog prijelaza, ali smo našli različite specifične topline u pretincima

Association of serum vitamin D and parathormone levels in patients of type 2 diabetes mellitus with diabetic retinopathy

The present study was aimed to evaluate the association of serum 25-hydroxy vitamin D and parathormone in 46 patients of type 2 diabetes mellitus with diabetic retinopathy [non-proliferative, (n=27); proliferative (n=19)]. Twenty one diabetic patients without retinopathy were taken as control. Serum 25-hydroxy vitamin D and intact parathyroid hormone were measured by chemiluminescence microparticle immunoassay. Concentration of 25-hydroxy vitamin D differed significantly among groups (p=0.018) and it was significantly lower in proliferative diabetic retinopathy than no diabetic retinopathy (p=0.003). Logistic regression analysis revealed that vitamin D deficiency [25-hydroxy vitamin D <20 ng/mL] was indepen-dently associated with development of diabetic retinopathy (p=0.007, OR 20.90, 95%CI 2.33-187.23). In conclusion, vitamin D deficiency is associated with diabetic retinopathy complicating type 2 diabetes mellitus

A study on association between non alcoholic fatty liver disease and ischemic heart disease in a tertiary care hospital

Background: Non-alcoholic fatty liver disease (NAFLD) is often an incidental finding in a large subset of Indian population, who because of their sedentary life style are more prone to ischaemic heart disease (IHD). This study was aimed at determining the association between NAFLD and IHD, with and without traditional risk factors for ischemic heart disease and to determine the relationship between the ischemic heart disease and severity of NAFLD. Materials and methods: It was a prospective comparative study among patients who got admitted in General Medicine ward or visited OPD of our institute from February 2020 to September 2021. Patients selected were divided into two groups- Study arm included patients with clinical features and investigations suggestive of ischemic heart disease. Control arm patients were age (+/-5years) matched people coming to hospital with infections/ illness not affecting liver, and without any history of ischaemic heart disease. We did check for NAFLD in these patients and tried to determine the association with IHD. Results: Significant number of patients (68.5%) had NAFLD in the study arm patients who were admitted for IHD in comparison to only 33.3% (p value-<0.001). Study arm had 31% patients with grade 2 or more NAFLD in comparison to 17% of control arm patients. There was significant association present between IHD and Severity of NAFLD (p value<0.05). Conclusion: NAFLD should be considered a risk factor of IHD, and should prompt clinicians to search for other cardiovascular risk factors and intervene at earliest
