Effect of dietary electrolyte balance and arginine to lysine ratio on hematological, antioxidant and immunological traits in dual-purpose breeding hens under cyclic heat stress condition
No full textA total of 245 hens and 35 cocks (32 weeks age) were assigned to seven treatment groups (five replicates with seven hens and one cock) to investigate the effect of dietary electrolyte balance (DEB) and arginine to lysine ratio (Arg/Lys) on birds’ physiological and biochemical traits under cyclic heat stress (CHS) condition. Birds were housed in an environmentally controlled facility having four sectors. The first group (positive control, PC) was kept under thermoneutral conditions and fed diet with DEB of 180 mEq and Arg/Lys of 1.25, whereas the other six treatments were kept in the second sector under CHS and fed diet with DEB and Arg/Lys equal to: 180 mEq and 1.25 (negative control, NC); 250 mEq and 1.25; 320 mEq and 1.25; 180 mEq and 1.37; 250 mEq and 1.37; 320 mEq and 1.37, respectively. Hens on NC group had significantly decreased red blood cells (RBCs), white blood cells (WBCs) and its fractions. The groups fed different DEB and Arg/Lys in diet significantly enhanced the blood parameters and plasma lipid profile compared NC group. Hens under CHS fed on 250 and 320 DEB with 1.37 Arg/Lys recorded the lowest concentration of low-density lipoprotein (LDL) compared with the other groups. Triiodothyronine (T3) activity was not differed among groups, while T4 activity in layer exposed to CHS (NC group) recorded the highest activity compared to PC. From findings, it can be concluded that laying hens fed a diet having DEB 250 mEq with 1.37 Arg/Lys could be successfully applied to counteract the adverse effect of CHS and to improve blood hematological and biochemical traits, antioxidants, and immunity response

Adapting authoritarianism: institutions and co-optation in Egypt and Syria
No full textThis PhD thesis compares Egypt and Syria’s authoritarian political systems. While the tendency in social science political research treats Egypt and Syria as similarly authoritarian, this research emphasizes differences between the two systems with special reference to institutions and co-optation. Rather than reducibly understanding Egypt and Syria as sharing similar histories, institutional arrangements, or ascribing to the oft-repeated convention that “Syria is Egypt but 10 years behind,” this thesis focuses on how events and individual histories shaped each states current institutional strengthens and weaknesses. Specifically, it explains the how varying institutional politicization or de-politicization affects each state’s capabilities for co-opting elite and non-elite individuals.
Beginning with a theoretical framework that considers the limited utility of democratization and transition theoretical approaches, the work underscores the persistence and durability of authoritarianism. Chapter two details the politicized institutional divergence between Egypt and Syria that began in the 1970s. Chapter three and four examines how institutional politicization or de-politicization affects elite and non-elite individual co-optation in Egypt and Syria. Chapter five discusses the study’s general conclusions and theoretical implications.
This thesis’s argument is that Egypt and Syria co-opt elites and non-elites differently because of the varying degrees of institutional politicization in each governance system. Rather than view one country as more politically developed than the other, this work argues that Syria’s political institutions are more politicized than their Egyptian counterparts. Syria’s political arena is, thus, described as politicized-patrimonialism. Syria’s politicized-patrimonial arena produces uneven co-optation of elites and non-elites as they are diffused through competing institutions. Conversely, the Egyptian political arena remains highly personalized as weak institutions and individuals are manipulated and molded according to the president’s ruling clique. This is referred to as personalized-patrimonialism. As a consequence, Egypt’s political establishment demonstrates more flexibility in ad hoc altering and adapting its arena depending on the emergence of crises.
This study’s theoretical implications suggest that, contrary to modernization and democratization theory’s adage that institutions lead to a political development, politicized institutions within a patrimonial order actually hinder regime adaptation because consensus is harder to achieve and maintain. It is within this context that Egypt’s de-politicized institutional framework advantages its top political elite. In this reading of Egyptian and Syrian politics, Egypt’s personalized political arena is more adaptable than Syria’s. These conclusions do not indicate that political reform is a process underway in either state
Dibenzyl ferrocene-1,1′-dicarboxylate
No full textIn the title compound, [Fe(C13H11O2)2], there are markedly different orientations of the two phenylmethoxycarbonyl substituents [O—C—C—C torsion angles = 84.5 (3) and 139.6 (2)°]. These orientations are mediated by a number of intermolecular C—H...O interactions, which result in a one-dimensional hydrogen-bonded network of molecules
Role of aspirin discontinuation in recurrence of ischemic cerebrovascular stroke
No full textAbstract Background Discontinuation of aspirin was suggested to be a risk factor for recurrent ischemic stroke; however, it was underestimated by most physicians. Objectives Study the effect of aspirin discontinuation in recurrence of ischemic cerebrovascular stroke. Patients and methods This is a descriptive case–control study, including 104 patients with recurrent ischemic stroke and 104 controls. Both sexes were included with age over 18 years. The following information was collected: history of aspirin discontinuation and cause and time of discontinuation. Investigations included brain CT or brain MRI for all patients, and the site of infarction was classified according to the Oxford classification. Results We found that 51% of patients discontinue aspirin compared to 28.8% of the control group. Nearly half of the patients (25/53) discontinue aspirin for 8–30 days before a stroke. Very high-risk patients were associated with stroke in 8–30 days of discontinuation, high-risk patients were associated with stroke in 181–365 days of discontinuation while moderate-risk patients were associated with stroke in 31–180 days of discontinuation. Conclusion Discontinuation of aspirin especially for a period of 8–30 days could increase the risk of recurrent ischemic stroke in patients with very high-risk and high-risk factors. Physicians need to educate patients about the importance of adherence of aspirin therapy

At present, that is, before the final review of the architecture and the stratigraphy, her statements are still fully valid, and have therefore in the main been inserted under 1.1 The excavations at Tell el-ʻAbd
Factors affecting treatment compliance of patients with multimorbidity
No full textNicolae Testemitanu State University of Medicine and Pharmacy, Republic of MoldovaIntroduction. Multimorbidity is a global health challenge, and it’s commonly defined as
the coexistence of 2 or more chronic diseases in the same individual. Roughly 50 million
people in Europe suffer from multimorbidity across all ages and backgrounds. The management of multimorbid patient is complex and it is influenced by different factors. The
compliance to treatment seems to affect the outcomes of multimorbid patients, but the
data in this regard are controversial.
The purpose of this research was to investigate the factors that affect compliance in multimorbidity, in order to improve the management of these patients and boost health outcomes.
Material and methods. A search strategy was developed, and PubMed database was
searched for literature from January 2016 to December 2020, as well as search of reference lists for systemic reviews and meta-analyses and Cochrane guidelines. Information
about publication date, subject category, author, country origin, title, abstract, and keywords were extracted, and the full texts were obtained for co-citation analysis. In total,
74 relevant studies and articles were used.
Results. Compliance is a multidimensional phenomenon, and it refers to the extent to
which a patient’s behavior aligns with agreed recommendations from healthcare providers. Multimorbidity is associated with multiple significant implications: whether physical, psychological, socioeconomic, and treatment challenges that ensue. Non-compliance
to prescribed treatment in multimorbid patients is determined by patient’s beliefs about
treatment, their knowledge about illness, socioeconomic status, level of treatment burden, and barriers such as costs or inadequate healthcare access. Five sets of compliance
determinants are recognized: patient-related (includes beliefs, self-efficacy, and
knowledge about illness); socioeconomic status (poor socioeconomic status, unemployment, lack of effective social support, unstable living conditions, and treatment burdens
such as medication costs); therapy-related (most notable is complexity of medical regimen, duration of treatment, side effects, and medical support availability to deal with
them); health system-related (represent issues due to poor communication); condition related (represent the illness-related demands faced by the patient including number of
conditions, severity of symptoms, level of disability, rate of progression and severity of
disease, as well as the availability of effective treatments). Based on revived research, in
order to increase the compliance in patients with multimorbidity, were applied different
strategies: improvement of the coordination of medical services, promotion of integrated
patient-centered care to optimize therapeutic regimens, increase treatment knowledge,
and engagement of the patient in treatment decisions.
Conclusions. Multimorbidity is associated with poorer medication adherence, and generates multiple challenges related to the complex healthcare needs, multiple consultations, fragmented healthcare services, polypharmacy, increased treatment burden and
costs. The relevant factors affecting compliance in multimorbidity were patient-related,
socioeconomic-related, therapy-related, health system-related, and condition-related. In
order to increase the compliance, we can use patient centered care, empowerment of the
patient and better coordination of care
Rice protein concentrate as a fish meal substitute in Oreochromis niloticus: Effects on immune response, intestinal cytokines, Aeromonas veronii resistance, and gut microbiota composition
No full textThe potential of rice protein concentrate (RPC) to substitute fishmeal (FM) protein in the diet of Oreochromis niloticus was assessed in a five-month-long feeding trial. Fishmeal protein was replaced by RPC at rates of 0% (control), 25%, 50%, and 75% (RPC0, RPC25, RPC50, and RPC75, respectively). RPC25 had no significant effect on antioxidant capacity (total antioxidant capacity; superoxide dismutase, catalase, and glutathione peroxidase activities) and immune indices (lysozyme, nitric oxide, antiprotease, and bactericidal activities) after one, two, and five months of feeding, while the values for these parameters were significantly lower in the RPC75 group compared to those in the RPC0 group. The RPC25 group showed higher mRNA levels of the intestinal cytokines IL-1 beta, IL-10 beta, TGF-beta, and TNF-alpha than the control group. In fish affected by Aeromonas veronii, the highest significant cumulative mortality was recorded in the RPC75 group, followed by the RPC50, RPC25, and control groups. Gut microbiome analyses showed a reduction in microbial diversity in response to the addition of RPC, regardless of the RPC content, and the composition of the community of the RPC samples differed from that of the control. RPC-enriched diets resulted in higher relative abundances of Bacteroidetes and Fusobacteria in the gut compared to that in the gut of the control fish. In summary, RPC can be used to replace up to 25% of the FM protein in the diet of O. niloticus, while improving the antioxidant capacity, immunocompetence, and disease resistance of the fish
Relationship between plasma fibrinogen level and obstructive sleep apnea
No full textAbstract Background Obstructive sleep apnea (OSA), which causes recurring hypoxemia owing to upper airway closure, is one of the most frequent sleep disorders. OSA patients are more prone to suffer cardiovascular disease (CVD) and stroke. One primary mechanism connecting OSA with cardiovascular problems is the prothrombotic state. Our goal in this research is to confirm the relationship between plasma fibrinogen levels and OSA. Results A case–control study involved 20 adults, non-obese participants who had been recently diagnosed with OSA, had never been treated for OSA before, and did not have any other preexisting conditions, and 20 controls underwent measurement of plasma fibrinogen levels following whole night polysomnography. The patient's plasma fibrinogen levels were substantially more significant than the controls' (399.8 ± 54.7 versus 309.8 ± 26.7 mg/dL, respectively), with a p-value of less than 0.001. Plasma fibrinogen levels in moderate and severe OSA (383.6 ± 20.6 mg/dL and 454.4 ± 25.6 mg/dL, respectively) were significantly higher than in controls (309.8 ± 26.7 mg/dL) (p < 0.001 and p < 0.001) and mild OSA patients (335 ± 27.8 mg/dL) (p = 0.013 and p < 0.001). Plasma fibrinogen levels were not significantly different between the controls and patients with mild OSA (p = 0.219). Apnea–hypopnea index, arousal index, and oxygen desaturation index showed positive correlations with plasma fibrinogen (r = 0.953, 0.888, and 0.894, p = < 0.001, < 0.001, and < 0.001, respectively). The total sleep time, sleep efficiency, N3%, REM%, and lowest oxygen saturation showed negative correlations (r = − 0.860, − 0.877, − 0.611, − 0.844, and − 0.745, p = < 0.001, < 0.001, < 0.001, and < 0.001, respectively). Conclusion Elevated levels of plasma fibrinogen in individuals with moderate-to-severe OSA may be attributed to sleep apnea and these increased levels could serve as a significant risk factor that establishes a connection between OSA and pathology of the cardiovascular and cerebrovascular systems. These results could significantly affect OSA diagnosis, therapy monitoring, and outcome
