Study of the effect of external use of a brown algae product on the structural-functional continuum
The authors, in a study on 25 outbred Wistar white rats weighing 180-200 g, determined the effect of Lamidana (a product from sea brown algae) on the structural-functional continuum, that is, the correlation of the functional activity of the liver parenchyma and its structural characteristics. Methods. The detoxifying function of the liver was studied by the duration of sleep of animals due to the action of anesthesia - intraperitoneal administration of sodium thiopental (estimate the rate of metabolism of thiopental, carried out by the cytochrome-P-450-dependent monooxygenase system of hepatocytes). The structural and functional state of the liver parenchyma was assessed according to the study of histological preparations. The results of the studies showed that under the influence of the external application of "Lamidin" in the test rats, the liver1s detoxification function is enhanced (significantly significant decrease in the duration of sleep of animals). At the same time, structural signs of increased functional activity of hepatocytes are determined in the parenchyma. Conclusions. The authors believe that "Lamidan", due to the peculiarities of its chemical composition, enhances the metabolic and functional activity of hepatocytes but does not damage the correlative relationships between the structure and function of hepatocytes
Supporting Introductory Test-Driven Labs with WebIDE
WebIDE is a new web-based development environment for entry-level programmers with two primary goals: minimize tool barriers to writing computer programs and introduce software engineering best practices early in a student\u27s educational career. Currently, WebIDE focuses on Test-Driven Learning (TDL) by using small iterative examples and introducing lock-step labs, which prevent the student from moving forward until they finish the current step. However, WebIDE does not require that labs follow TDL. Instructors can write their own labs for WebIDE using any software engineering or pedagogical approach. Likewise, instructors can build custom evaluators - written in any language - to support their approach and provide detailed error messages to students. We report on a pilot study in a CS0 course where students were split into two groups, one that used WebIDE and one that didn\u27t. The WebIDE group showed a significant improvement in performance when writing a simple Android application. Additionally, among students with some programming experience, the WebIDE group was more proficient in writing unit tests

Justification of the renoprotective action of the mixture of sodium chloride and sodium bicarbonate solutions in phenylhydrazine intoxication
The authors conducted a study on 35 white Wistar outbred rats to investigate the possibility of correcting acute kidney damage induced by the administration of phenylhydrazine at a dose of 100 mg/kg by introducing a mixture of sodium chloride and sodium bicarbonate solutions into the body.
The research results identified changes in the kidneys upon phenylhydrazine administration, including the loss of some capillary glomeruli, eosinophilic deposits in Bowman's spaces and tubular lumens, and lymphoid infiltration in the interstitium. Rats receiving a mixture of sodium chloride and sodium bicarbonate solutions in their drinking water showed positive changes in their kidneys: no loss of capillary glomeruli was observed, and eosinophilic deposits were absent in most tubules. Lymphocyte aggregation was only observed around some renal vessels. The authors suggest that the intake of additional sodium and bicarbonate into the body, along with alkalinization of the primary urine, promotes the excretion of hemolysis products caused by phenylhydrazine, which contributes to renoprotection and preservation of renal parenchyma
Probabilistic Temporal Databases, I: Algebra
Dyreson and Snodgrass have drawn attention to the fact that in many
temporal database applications, there is often uncertainty present
about the start time of events, the end time of events, the duration of
events, etc. When the granularity of time is small (e.g. milliseconds),
a statement such as "Packet p was shipped sometime during the
first 5 days of January, 1998" leads to a massive amount of uncertainty
(5 times 24 times 60 times 60 times 1000) possibilities. As noted by
Zaniolo et. al., past
attempts to deal with uncertainty in databases have been restricted
to relatively small amounts of uncertainty in attributes.
Dyreson and Snodgrass have taken an important first
step towards solving this problem.
In this paper, we first introduce the syntax of Temporal-Probabilistic
(TP) relations and then show how they can be converted to an explicit,
significantly more space-consuming form called Annotated Relations.
We then present a {\em Theoretical Annotated Temporal
Algebra} (TATA). Being explicit, TATA
is convenient for specifying how the
algebraic operations should behave, but is impractical to use because
annotated relations are overwhelmingly large.
Next, we present a Temporal Probabilistic Algebra (TPA).
We show that our definition of the TP-Algebra
provides a correct implementation of TATA despite the fact that
it operates on implicit, succinct TP-relations instead of the
overwhelmingly large annotated relations.
Finally, we report on timings for an implementation of the TP-Algebra
built on top of ODBC.

Social health and change in cognitive capability among older adults:findings from four European longitudinal studies
Introduction: In this study we examine whether social health markers measured at baseline are associated with differences in cognitive capability and in the rate of cognitive decline over an 11-to-18-year period among older adults and compare results across studies. Methods: We applied an integrated data analysis approach to 16,858 participants (mean age 65 years; 56% female) from the National Survey for Health and Development (NSHD), the English Longitudinal Study of Aging (ELSA), the Swedish National Study on Aging and Care in Kungsholmen (SNAC-K), and the Rotterdam Study. We used multilevel models to examine social health in relation to cognitive capability and the rate of cognitive decline. Results: Pooled estimates show distinct relationships between markers of social health and cognitive domains e.g., a large network size (≥6 people vs none) was associated with higher executive function (0.17 SD[95%CI:0.0, 0.34], I2=27%) but not with memory (0.08 SD[95%CI: -0.02, 0.18], I2=19%). We also observed pooled associations between being married or cohabiting, having a large network size and participating in social activities with slower decline in cognitive capability, however estimates were close to zero e.g., 0.01SD/year [95%CI: 0.01 to 0.02] I2=19% for marital status and executive function. There were clear study-specific differences: results for average processing speed were the most homogenous and results for average memory were the most heterogenous. Conclusion: Overall, markers of good social health have a positive association with cognitive capability. However, we found differential associations between specific markers of social health and cognitive domains and differences between studies. These findings highlight the importance of examining between study differences and considering context specificity of findings in developing and deploying any intervention
