Integral Inequalities of Hermite-Hadamard Type Via Green Function and Applications
In this study, we establish some Hermite- Hadamard type inequalities for functions whose second derivatives absolute value are convex. In accordance with this purpose, we obtain an identity using Green\u27s function. Then using this equality we get our main results
Coenological data on temperate semidesert sandy grasslands in Hungary
A neighbourding -quadrate transect study was conducted in order to examine the possibile relationship between small scale topography and coenotaxa occurrence and cover in subassociations of Festucetum vaginataeRapaics ex SoĂł 1929 sandy grassland plant community near FĂŒlöphĂĄza. These investigations served as a starting point in later soil seed bank studies. Cover of species was recorded in three transects of different exposition starting on the top of different dunes and ending in the depressions. Subassociations and facies forming species of the community occurred in all investigated transects. Parts of the transects could not have been classified unambiguously into any of the coenotaxa mentioned in the literature. In these zones the charactersitic species of the different subbasociations and facies were occurding together. These patches are propbably also the ones where changes in dominance relations and simultaneous spread of a species can relatively easily happen, as it is the case with Cleistogenes serotina. Annual vegetation of the open sandy grassland, ond the other hand, has occured only in the transition zones, between the subassociations or facies. In these transects moss-lichen synusia were peresent usually in the subassociation Festucetum vaginatae pennatae Kerner 1863
Neutrophil to lymphocyte ratio as an indicative of diabetic control level in type 2 diabetes mellitus
Background: Type 2 diabetes mellitus is associated with chronic low
grade inflammation. One of the novel inflammatory markers is hemogram
derived neutrophil to lymphocyte ratio (NLR). Objective: We aimed to
compare NLR levels of diabetic subjects and healthy controls and to
observe possible correlation between NLR and HbA1c. Methods: Medical
data of type 2 diabetic subjects admitted to out-patient clinics of our
institution between April to July in 2017 were obtained from database
and retrospectively analyzed. Control group was chosen from healthy
subjects who visited our institution for a routine check-up.
Anthropometric measures, laboratory data, including, HbA1c, NLR were
recorded. Results: Median NLR of the type 2 DM group 2.44 (1.9) was
significantly elevated when compared to healthy controls (1.5 (0.9),
(p<0.001). In addition, a Pearson\u2019s correlation test revealed
that NLR was strongly correlated with age (r=0.26, p=0.008), fasting
plasma glucose (r=0.38, p<0.001), and HbA1c (r=0.49, p<0.001).
Conclusion: Elevated NLR in otherwise healthy subjects may be
indicative of underlying impaired glucose metabolism and moreover, NLR
should be used as a marker of diabetic control level in addition to
HbA1c in type 2 diabetic subjects. DOI:

Restoration of photosystem II photochemistry and carbon assimilation and related changes in chlorophyll and protein contents during the rehydration of desiccated Xerophyta scabrida leaves
Recovery of photosynthesis in rehydrating desiccated leaves of the poikilochlorophyllous desiccation-tolerant plant Xerophyta scabrida was investigated. Detached leaves were remoistened under 12âh light/dark cycles for 96âh. Water, chlorophyll (Chl), and protein contents, Chl fluorescence, photosynthesisâCO2 concentration response, and the amount and activity of Rubisco were measured at intervals during the rehydration period. Leaf relative water contents reached 87% in 12âh and full turgor in 96âh. Chl synthesis was slower before than after 24âh, and Chla:Chlb ratios changed from 0.13 to 2.6 in 48âh. The maximum quantum efficiency recovered faster during rehydration than the photosystem II operating efficiency and the efficiency factor, which is known to depend mainly on the use of the electron transport chain products. From 24âh to 96âh of rehydration, net carbon fixation was Rubisco limited, rather than electron transport limited. Total Rubisco activity increased during rehydration more than the Rubisco protein content. Desiccated leaves contained, in a close to functional state, more than half the amount of the Rubisco protein present in rehydrated leaves. The results suggest that in X. scabrida leaves Rubisco adopts a special, protective conformation and recovers its activity during rehydration through modifications in redox status
