Abstract
Targeting cardiac remodeling is regarded as a key therapeutic strategy for heart failure. Kielin/chordin-like protein (KCP) is a secretory protein with 18 cysteine-rich domains and associated with kidney and liver fibrosis. However, the relationship between KCP and cardiac remodeling remains unclear. Here, we aimed to investigate the role of KCP in cardiac remodeling induced by pressure overload and explore its potential mechanisms. Left ventricular (LV) KCP expression was measured with real-time quantitative PCR, western blotting, and immunofluorescence staining in pressure overload-induced cardiac remodeling in mice. Cardiac function and remodeling were evaluated in wide-type (WT) mice and KCP knockout (KO) mice by echocardiography, which were further confirmed by histological analysis with hematoxylin and eosin and Masson staining. RNA sequence was performed with LV tissue from WT and KO mice to identify differentially expressed genes and related signaling pathways. Primary cardiac fibroblasts (CFs) were used to validate the regulatory role and potential mechanisms of KCP during fibrosis. KCP was down-regulated in the progression of cardiac remodeling induced by pressure overload, and was mainly expressed in fibroblasts. KCP deficiency significantly aggravated pressure overload-induced cardiac dysfunction and remodeling. RNA sequence revealed that the role of KCP deficiency in cardiac remodeling was associated with cell division, cell cycle, and P53 signaling pathway, while cyclin B1 (CCNB1) was the most significantly up-regulated gene. Further investigation in vivo and in vitro suggested that KCP deficiency promoted the proliferation of CFs via P53/P21/CCNB1 pathway. Taken together, these results suggested that KCP deficiency aggravates cardiac dysfunction and remodeling induced by pressure overload via P53/P21/CCNB1 signaling in mice.

Abstract
Objective: To investigate the clinicopathological characteristics of gastrointestinal tumors with SWI/SNF complex deficiency and to perform a prognostic analysis of the patients. Methods: Gastrointestinal tumor cases with SWI/SNF complex deficiency expression diagnosed at the Department of Pathology, Zhongshan Hospital, Fudan University, Shanghai, China from August 2021 to May 2023 were collected. Hematoxylin and eosin (HE) stained slides were reviewed, and immunohistochemical results were analyzed. Clinical and pathological information was recorded, and relevant literature was reviewed. Results: A total of 36 cases of gastrointestinal tumor with loss of SWI/SNF complex expression were identified, including 28 males (77.8%) and 8 females (22.2%). The average age at diagnosis was 70 years (range 48-85 years). Clinical staging showed 3 cases in stage Ⅰ (8.3%), 12 cases in stage Ⅱ (33.3%), 19 cases in stage Ⅲ (52.8%), and 2 cases in stage Ⅳ (5.6%). Complete or partial loss of ARID1A expression was observed in 20 cases (55.6%); complete or partial loss of SMARCA2 expression was observed in 24 cases (66.7%). SMARCA4 exhibited complete loss of expression in 4 cases (11.1%). Eleven cases (30.6%) showed concurrent complete or partial losses of both ARID1A and SMARCA2 expression. Twelve cases (33.3%) had mismatch repair protein deficiency, all of which were characterized by MLH1/PMS2 absence. Mismatch repair protein deficiency was associated with loss of ARID1A expression (P<0.01). Patients with mismatch repair protein deficiency were also associated with earlier clinical stage and a lower risk of lymph node metastasis compared to the ones with intact mismatch repair proteins (P<0.05). Conclusions: SWI/SNF complex deficiency in gastrointestinal tumors is associated with dedifferentiation and often accompanied by mismatch repair protein deficiency. Compared to the cases with intact mismatch repair proteins, the cases with defective mismatch repair protein have an earlier clinical stage and a lower risk of lymph node metastasis.

Abstract
The relationship between the expression of the SATB2 and CDX2 proteins and common molecular changes and clinical prognosis in colorectal cancer (CRC) still needs further clarification. We collected 1180 cases of CRC and explored the association between the expression of SATB2 and CDX2 and clinicopathological characteristics, molecular alterations, and overall survival of CRC using whole-slide immunohistochemistry. Our results showed that negative expression of SATB2 and CDX2 was more common in MMR-protein-deficient CRC than in MMR-protein-proficient CRC (15.8% vs. 6.0%, P = 0.001; 14.5% vs. 4.0%, P = 0.000, respectively). Negative expression of SATB2 and CDX2 was more common in BRAF-mutant CRC than in BRAF wild-type CRC (17.2% vs. 6.1%, P = 0.003; 13.8% vs. 4. 2%; P = 0.004, respectively). There was no relationship between SATB2 and/or CDX2 negative expression and KRAS, NRAS, and PIK3CA mutations. The lack of expression of SATB2 and CDX2 was associated with poor histopathological features of CRC. In multivariate analysis, negative expression of SATB2 (P = 0.030), negative expression of CDX2 (P = 0.043) and late clinical stage (P = 0.000) were associated with decreased overall survival of CRC. In conclusion, the lack of SATB2 and CDX2 expression in CRC was associated with MMR protein deficiency and BRAF mutation, but not with KRAS, NRAS and PIK3CA mutation. SATB2 and CDX2 are prognostic biomarkers in patients with CRC.

Abstract
Germline mutations in mismatch repair (MMR) genes (MLH1, MSH2, MSH6, PMS2) can be mono-allelic or biallelic, resulting in a Lynch syndrome (LS) or constitutional mismatch repair deficiency (CMMRD) syndrome respectively. Glioma arising in the setting of MMR deficiency is uncommon. We describe two pediatric patients with high-grade glioma (HGG) and associated MMR protein deficiency. On histomorphology both cases showed HGG with astrocytic morphology and prominent multinucleated tumor cells. On immunohistochemistry, the first case was negative for IDH1 p.R132H showed loss of ATRX and p53 positivity. The second case was positive for IDH1 p.R132H and p53, but showed retained expression of ATRX. The histomorphology in both cases and additionally IDH mutation with retained ATRX in the second case, prompted us to test for MMR protein deficiency which was carried out by immunohistochemistry (IHC). One case revealed an immunostaining pattern suggestive of CMMRD while the other was suggestive of LS. Both the cases showed good response to surgery and radio-chemotherapy in the follow-up available. Our cases highlight the importance of testing for MMR proteins by simple IHC, in the setting of appropriate clinical scenario, histopathological and immunohistochemical findings. The recognition of these tumors is extremely important to guide further treatment and prompt family screening.

Abstract
Insufficient protein intake and cognitive decline are common in older adults; however, there have been few studies on low protein risk screening and complex nutrient interventions for elderly individuals in rural communities. This study aimed to evaluate the effect of dietary multinutrient soy flour (MNSF) on body composition and cognitive function in elderly individuals who are at risk of protein deficiency in a randomized, double-blind, placebo-controlled clinical trial. Nutritional interventions were given to those found to have low protein levels using bioelectrical impedance analysis (BIA). Among 733 older adults screened, 62 participants were included and randomly assigned into two groups, one taking soy flour and the other taking MNSF for 12 weeks. A previous cross-sectional survey found that 35.1% of the elderly people with an average age of 71.61 ± 5.94 years had an inadequate body protein mass proportion. After the intervention, the MNSF group demonstrated a significant improvement in protein mass, muscle mass, mineral levels, skeletal muscle mass, and fat-free mass compared with baseline (all P < 0.05), as well as a better upward trend compared with the soy flour group (P = 0.08; P = 0.07; P = 0.05; P = 0.08; P = 0.07). Regarding the mini-mental state examination (MMSE) scores, the MNSF group showed a significant decrease after 12 weeks (P < 0.05), which were significantly different compared with the soy flour group (P < 0.05). In the future, the application of MNSF as a food-based supplement to improve nutrition and delay cognitive decline in older adults at the risk of protein deficiency may be considered.

Abstract
BACKGROUND This study aimed to analyze the correlation between the 3-year disease-free survival (DFS) and mismatch repair (MMR) protein levels in patients with type 1 endometrial carcinoma. Many studies have reported different results regarding the role of MMR in the prognosis of endometrial carcinoma; therefore, we aimed to identify this association in our hospital. METHODS This observational study employed a historical cohort design and included patients with type 1 endometrial carcinoma who underwent surgery at Dr. Soetomo Hospital between January 2017 and December 2019. Medical records and paraffin blocks meeting these criteria were obtained. MMR proteins (MLH1 and MSH2) were assessed using immunohistochemistry. RESULTS A total of 46 patients with type 1 endometrial carcinoma were analyzed. We observed MMR deficiency (dMMR) in 12 patients (26.1%) and MMR proficiency (pMMR) in 34 patients (73.9%). Of the 12 patients with dMMR, nine cases (75%) were diagnosed as stage I and 7 (58.33%) as low grade. The 3-year DFS in patients with dMMR and pMMR was 83.3% and 67.6%, respectively (Hazard Ratio 2.31, 95% CI 0.5135-10.475, p=0.27). Higher stages had a 5.42 times increased risk of recurrence (95% CI 1.3378-21.9358, p=0.018). Higher histopathological grades were also associated with 8.65 times increased risk of recurrence (95% CI 2.5020-29.8738, p=0.001). CONCLUSION Patients with dMMR had a better DFS compared to those with pMMR; however, the difference was not statistically significant. The tumor stage and histopathological grade were independent risk factors for recurrence.

Abstract
OBJECTIVE Investigating for mismatch repair protein deficiency (MMRd), microsatellite instability (MSI), and Lynch syndrome (LS) is widely accepted in endometrial cancer, but knowledge is limited on its value in epithelial ovarian cancer (EOC). The primary objective was to evaluate the prevalence of mismatch repair protein deficiency (MMRd), microsatellite instability (MSI)-high, and Lynch syndrome (LS) in epithelial ovarian cancer (EOC), as well as the diagnostic accuracy of LS screening tests. The secondary objective was to determine the prevalence of MMRd, MSI-high, and LS in synchronous ovarian endometrial cancer and in histological subtypes. METHODS We systematically searched the MEDLINE, Epub Ahead of Print, MEDLINE In-Process and Other Non-Indexed Citations, Cochrane Central Register of Controlled Trials, and Embase databases. We included studies analysing MMR, MSI, and/or LS by sequencing. RESULTS A total of 55 studies were included. The prevalence of MMRd, MSI-high, and LS in EOC was 6% (95% confidence interval (CI) 5-8%), 13% (95% CI 12-15%), and 2% (95% CI 1-3%) respectively. Hypermethylation was present in 76% of patients with MLH1 deficiency (95% CI 64-84%). The MMRd prevalence was highest in endometrioid (12%) followed by non-serous non-mucinous (9%) and lowest in serous (1%) histological subtypes. MSI-high prevalence was highest in endometrioid (12%) and non-serous non-mucinous (12%) and lowest in serous (9%) histological subtypes. Synchronous and endometrioid EOC had the highest prevalence of LS pathogenic variants at 7% and 3% respectively, with serous having lowest prevalence (1%). Synchronous ovarian and endometrial cancers had highest rates of MMRd (28%) and MSI-high (28%). Sensitivity was highest for IHC (91.1%) and IHC with MSI (92.8%), while specificity was highest for IHC with methylation (92.3%). CONCLUSION MMRd and germline LS testing should be considered for non-serous non-mucinous EOC, particularly for endometrioid. PRECIS The rates of mismatch repair deficiency, microsatellite instability high, and mismatch repair germline mutations are highest in endometrioid subtype and non-serous non-mucinous ovarian cancer. The rates are lowest in serous histologic subtype.

Abstract
It has been reported that mismatch repair deficient (d-MMR) tumors show sensitivity to immune checkpoint inhibitors. We aimed to evaluate the correlation of d-MMR and PD-1/PD-L1 expression in invasive urothelial carcinoma of the bladder. Tissue microarray (TMA) tissues were stained PD-1/PD-L1 and MMR proteins. The expression ratio of these markers has been compared with histopathologic parameters. d-MMR tumors were more superficial muscle invasive (p = 0.012). When the d-MMR, and PD-1/PD-L1 expression ratios were examined, a significant correlation was obtained between the d-MMR and PD-L1 expression ratio of > 5% in both the tumor and immune cells (p = 0.02 and p = 0.004, respectively). The expression ratio was higher in the patients without MMR loss. PD-1 and PD-L1expression in those with MSH6 loss was one or none. When PD1/PDL1 expression was compared with histopathological parameters, a significant relationship was observed between tumor grade and depth of muscle invasion. PD-L1 expression was not observed in the superficial muscle invasive tumors. This study was shown the status of d-MMR and PD-1/PD-L1 in invasive urothelial cancers and their correlation with prognostic markers. PD-1/PD-L1 expression may contribute to the progression and poor prognosis of bladder cancer. However, further studies are required to research the clinical utility.

Abstract
PURPOSE The present study investigated whether maternal curcumin supplementation might protect against intra-uterine growth retardation (IUGR) induced intestinal damage and modulate gut microbiota in male mice offspring. METHODS In total, 36 C57BL/6 mice (24 females and 12 males, 6-8 weeks old) were randomly divided into three groups based on the diet before and throughout pregnancy and lactation: (1) normal protein (19%), (2) low protein (8%), and (3) low protein (8%) + 600 mg kg-1 curcumin. Offspring were administered a control diet until postnatal day 35. RESULTS Maternal curcumin supplementation could normalize the maternal protein deficiency-induced decrease in jejunal SOD activity (NP = 200.40 ± 10.58 U/mg protein; LP = 153.30 ± 5.51 U/mg protein; LPC = 185.40 ± 9.52 U/mg protein; P < 0.05) and T-AOC content (NP = 138.90 ± 17.51 U/mg protein; LP = 84.53 ± 5.42 U/mg protein; LPC = 99.73 ± 12.88 U/mg protein; P < 0.05) in the mice offspring. Maternal curcumin supplementation increased the maternal low protein diet-induced decline in the ratio of villus height-to-crypt depth (NP = 2.23 ± 0.19; LP = 1.90 ± 0.06; LPC = 2.56 ± 0.20; P < 0.05), the number of goblet cells (NP = 12.72 ± 1.16; LP = 7.04 ± 0.53; LPC = 13.10 ± 1.17; P < 0.05), and the ratio of PCNA-positive cells (NP = 13.59 ± 1.13%; LP = 2.42 ± 0.74%; LPC = 6.90 ± 0.96%; P < 0.05). It also reversed the maternal protein deficiency-induced increase of the body weight (NP = 13.00 ± 0.48 g; LP = 16.49 ± 0.75 g; LPC = 10.65 ± 1.12 g; P < 0.05), the serum glucose levels (NP = 5.32 ± 0.28 mmol/L; LP = 6.82 ± 0.33 mmol/L; LPC = 4.69 ± 0.35 mmol/L; P < 0.05), and the jejunal apoptotic index (NP = 6.50 ± 1.58%; LP = 10.65 ± 0.75%; LPC = 5.24 ± 0.71%; P < 0.05). Additionally, maternal curcumin supplementation enhanced the gene expression level of Nrf2 (NP = 1.00 ± 0.12; LP = 0.73 ± 0.10; LPC = 1.34 ± 0.12; P < 0.05), Sod2 (NP = 1.00 ± 0.04; LP = 0.85 ± 0.04; LPC = 1.04 ± 0.04; P < 0.05) and Ocln (NP = 1.00 ± 0.09; LP = 0.94 ± 0.10; LPC = 1.47 ± 0.09; P < 0.05) in the jejunum. Furthermore, maternal curcumin supplementation normalized the relative abundance of Lactobacillus (NP = 31.56 ± 6.19%; LP = 7.60 ± 2.33%; LPC = 17.79 ± 2.41%; P < 0.05) and Desulfovibrio (NP = 3.63 ± 0.93%; LP = 20.73 ± 3.96%; LPC = 13.96 ± 4.23%; P < 0.05), and the ratio of Firmicutes/Bacteroidota (NP = 2.84 ± 0.64; LP = 1.21 ± 0.30; LPC = 1.79 ± 0.15; P < 0.05). Moreover, Lactobacillus was positively correlated with the SOD activity, and it was negatively correlated with Il - 1β expression (P < 0.05). Desulfovibrio was negatively correlated with the SOD activity and the jejunal expression of Sod1, Bcl - 2, Card11, and Zo - 1 (P < 0.05). CONCLUSIONS Maternal curcumin supplementation could improve intestinal integrity, oxidative status, and gut microbiota in male mice offspring with IUGR.

Abstract
LPS-responsive beige-like anchor protein (LRBA) deficiency is a primary immunodeficiency caused by a mutation in the LRBA gene. Affected individuals present with a variety of clinical symptoms including hypogammaglobulinemia, recurrent infections, splenomegaly, hepatomegaly, and autoimmune cytopenias. Except for hypogammaglobulinemia, the remaining features resemble autoimmune lymphoproliferative syndrome (ALPS). Here, we report the case of a 14-year-old boy with the ALPS phenotype, eventually diagnosed with LRBA deficiency. He presented with lymphadenopathy and hepatosplenomegaly, along with autoimmune cytopenia. Due to recurrent infections and worsening gastrointestinal symptoms, whole-exome sequencing was conducted and revealed a novel homozygous pathogenic variant in the LRBA gene (c.534del; p.9Asp179IIef*16). The patient recently suffered from clinical deterioration due to SARS-COV-2 which appears to have triggered an acute worsening of his existing Cytomegalovirus colitis leading to an eventual demise. A literature search for reported LRBA deficient patients with ALPS-like phenotype revealed 11 patients. The most common clinical presentations in LRBA patients with ALPS-like phenotype included autoimmunity (100%), splenomegaly (91%), lymphadenopathy (36.4%), and respiratory tract infections (63.6%). LRBA deficiency is unique in the fact that it encompasses immune deficiency, autoimmunity, and lymphoproliferation. In children with multiple symptoms related to these domains, a genetic diagnosis is necessary to ensure tailored and precise medical therapy.

Abstract
OBJECTIVE To explore the characteristics of SLC25A13 gene variants in 16 infants with neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD). METHODS The infants were subjected to high-throughput DNA sequencing for coding exons and flanking regions of the target genes. Suspected variants were verified by Sanger sequencing and bioinformatic analysis. RESULTS Among the 16 NICCD cases, 15 were found to harbor pathogenic variants. Among these, IVS14-9A>G, c.1640G>A, c.762T>A, c.736delG, c.1098Tdel and c.851G>A were previously unreported. CONCLUSION Six novel SLC25A13 variants were found by high-throughput sequencing, which has enriched the spectrum of SLC25A13 gene variants and provided a basis for genetic counseling and prenatal diagnosis.

Abstract
BACKGROUND Polytrauma patients are at risk of considerable harm from malnutrition due to the metabolic response to trauma. However, there is little knowledge of (the risk of) malnutrition and its consequences in these patients. Recognition of sub-optimally nourished polytrauma patients and their nutritional needs is crucial to prevent complications and optimize their clinical outcomes. AIM The primary objective is to investigate whether polytrauma patients admitted to the Intensive Care Unit (ICU) who have or develop malnutrition have a higher complication rate than patients who are and remain well nourished. Secondary objectives are to determine the prevalence of pre-existent and in-hospital acquired malnutrition in these patients, to assess the association between malnutrition and long-term outcomes, and to determine the association between serum biomarkers (albumin and pre-albumin) and malnutrition. METHODS This international observational prospective cohort study will be performed at three Level-1 trauma centers in the United States and two Level-1 centers in the Netherlands. Adult polytrauma patients (Injury Severity Score ≥16) admitted to the ICU of one of the participating centers directly from the Emergency Department are eligible for inclusion. Nutritional status and risk of malnutrition will be assessed using the Subjective Global Assessment (SGA) scale and Nutritional Risk in Critically Ill (NUTRIC) score, respectively. Nutritional intake, biomarkers and complications will be collected daily. Patients will be followed up to one year after discharge for long-term outcomes. CONCLUSIONS This international prospective cohort study aims to gain more insight into the effect and consequences of malnutrition in polytrauma patients admitted to the ICU.

Abstract
BACKGROUND & AIMS Protein malnutrition (PM) affects hematopoiesis leading to bone marrow (BM) hypoplasia and arrests hematopoietic stem cells (HSC) in G0/G1 cell cycle phases, which cause anemia and leukopenia. Hematopoiesis is mainly regulated by BM niches where endothelial cells (EC) present a key regulatory role. Thus, our objective is to evaluate whether PM affects the modulatory capacity of EC on hematopoiesis. METHODS C57BL/6 male mice received for 5 weeks a normal protein diet (12% casein) or a low protein diet (2% casein). MSC were isolated and differentiated in vitro into EC and the synthesis of SCF, Ang-1, CXCL-12, IL-11, TGF-β and G-CSF were evaluated. The HSC and hematopoietic progenitors were quantified and the EC capacity to modulate the hematopoietic system was also evaluated. Moreover, the ability of PM bone marrow to support hematopoieisis was assessed by proliferation of infused leukemic myelo-monoblasts cells. RESULTS PM decreases HSC and hematopoietic progenitor pool and promotes cell cycle arrest and a lower proliferation rate of leukemic myelo-monoblasts. PM also committed hematopoietic regulatory characteristics from EC, resulting in the modification of both cell cycle pattern and hematopoietic differentiation. CONCLUSION BM microenvironment is compromised in PM, and since PM disturbs EC, it becomes one of the factors responsible for the hematopoietic cell cycle arrest and impairment of HSC differentiation.

Abstract
The 26S proteasome is a large protease complex that selectively degrades ubiquitinated proteins. It comprises 33 distinct subunits, each of which differ in function and structure, and which cannot be substituted by the other subunits. Owing to its complicated structure, the biogenesis of the 26S proteasome is elaborately regulated at the transcription, translation, and molecular assembly levels. Recent studies revealed that Nrf1 (NFE2L1) is a transcription factor that upregulates the expression of all the proteasome subunit genes in a concerted manner, especially during proteasome impairment in mammalian cells. In this review, we summarize current knowledge regarding the transcriptional regulation of the proteasome and recent findings concerning the regulation of Nrf1 transcription activity.

Abstract
The ferrokinetic indices of blood serum of rats with acetaminophen-induced hepatitis under the conditions of alimentary deprivation of protein were assessed in the work. Research was conducted on 4 groups of animals: 1 - control; 2 - rats maintained on low-protein diet; 3 - rats with acute acetaminophen-induced hepatitis, maintained on full-value ration, 4 - rats with acute acetaminophen-induced hepatitis, maintained under the conditions of alimentary deprivation of protein. The serum iron content of and serum iron binding capacity were determined colorimetrically,% of the transferrin iron saturation - as a ratio of serum iron concentration to maximal iron binding capacity of serum transferrin. The presence of hemosiderin inclusions and the character of hemosiderosis were determined in the liver sections, stained by Perls method. Qualitative determination of C-reactive protein in blood serum was carried out by immunoenzymatic method. It is shown, that in protein-deficiency rats any significant changes of iron metabolism indices and hemosiderin accumu- lation weren't observed. At the same time in rats with acetaminophen-induced hepatitis the 5-fold increase of the serum iron content against the background non-significant increase of serum iron binding capacity and the 2-fold increase of the transferrin iron saturation is established. Simultaneously in the hepatocytes and reticuloendothelial system cells the accumulation of hemosiderin in the low dispersion form is observed, equating the second degree of hemosiderosis on the background emerging of C-reactive protein in serum. In protein-deficiency rats with toxic liver injury an abrupt increase of serum iron against the background reduction of the total serum iron binding capacity and maximal saturation of transferrin by iron ions is observed. It is established, that for animals from current group the third degree of mixed type hemosiderosis and the intensification of the inflammatory reaction in liver is characterstic. Conclusion was made, that alimentary deprivation of protein under the conditions of toxic liver injury is the critical factor for structural-functional state of liver, being accompanied by the iron metabolism disturbances, development of hemosiderosis and intensification of the inflammatory reaction in liver. Research results may be used for the biochemical rationale of the therapeutic approaches for the elimination and correction of the toxic liver injury consequences.

Abstract
Research of the diet of students of the Faculty of Physical Education found discrepancy of caloric content and correlation of macro- and micronutrients to physiological norms accompanied by a deficiency of some mineral elements. Thus, this research found discrepancy of a diet in caloric content and correlation of macro- and micronutrients to physiological norms. Calorie deficiency in both groups is caused for lack of all macro- and micronutrients, but mostly for lack of carbohydrates with an average glycemic index, fruit, and vegetables that have prebiotic properties and mineral-rich elements. Deficiency in the diet of young men 9.6% of the total protein and 23.5% of carbohydrates was accompanied for lack 15.5% of calcium. In the group of girls the results showed a decrease of the required amounts of calcium, magnesium and iron of 36.4; 7.5 and 1.5% respectively, which was displayed against a background of reducing the consumption of the total protein 25.1 and 36.0% of carbohydrates. As a result, basic nutrition of students practicing sports requires rationalization and adjustment. To improve the biological value of the diet it is advisable for students to use daily dairy products and other sources of animal protein in their diets. It is also necessary to introduce fruit and vegetables as a source of dietary fibers and mineral elements. Created in both groups deficiency of calcium and biologically high-grade proteins of animal origin can be eliminated by various dairy products in which calcium and phosphorus are in easily digestible form and in a balanced quantity. Despite the considerable amount of calcium in many foods (meat, bread, cereals, vegetables) calcium is assimilated with difficulty from these products. The exception is the calcium of milk, curd, cheese and other dairy products. The ration between calcium and phosphorus in milk is 1:1-1.4:1. For example, taking 0.5 liters of milk provides 600 mg of assimilable calcium intake.

Abstract
Balb/c mice infected with the gastrointestinal nematode Heligmosomoides bakeri were fed protein sufficient (PS, 24%) or deficient (PD, 3%) diets to investigate whether diet, infection or dose of larval challenge (0, 100 or 200 larvae) influenced gut pathophysiology and inflammation. Among the PS mice, worms were more posteriorad in the intestine of mice infected with 200 compared with 100 larvae, suggesting active expulsion in the more heavily infected mice. This was consistent with the positive correlation between worm numbers and fluid leakage in PS mice; similar patterns were not detected in the PD mice. Infection also induced villus atrophy, which was more pronounced in PS than in PD mice. Our cytokine screening array indicated that infection in PD mice elevated a wide range of pro-inflammatory cytokines and chemokines. Whereas serum leptin concentrations were higher in PD mice, monocyte chemotactic protein-5 (MCP-5) in serum increased with increasing larval dose and concentrations were lower in PD than PS mice. We suggest that elevated MCP-5 together with villus atrophy may contribute to the apparent dose-dependent expulsion of H. bakeri from PS mice but that delayed expulsion in PD mice appeared related to a predominant Th1 cytokine profile that may be driven by leptin.

Abstract
INTRODUCTION Independent of etiology, the hepatic microvesicular steatosis has a worse prognosis compared with macrovesicular steatosis. Proliferation compensates for apoptosis and reflects regenerative mechanisms following liver injury. It is unknown whether these two types of fatty liver have differences in regenerative capacity and apoptosis, which could have an impact on their prognosis. METHODS Two groups of pigs were studied for 72 days under a protein-deficient diet. One group received only protein-deficient diet (n=6), the other was treated in addition to the diet with 6g ethanol/kg/day by means of a percutaneous intragastric catheter (n=6). The rate of proliferating and apoptotic hepatocytes was determined, respectively, by proliferation cell nuclear antigen (PCNA) and ISEL/TUNEL staining for apoptosis in liver biopsies with similar steatosis grade in pigs with micro- or macrovesicular fatty liver. RESULTS The ethanol-treated group developed microvesicular steatosis, the other group developed macrovesicular steatosis. Proliferation index was significantly increased in macrovesicular in comparison with microvesicular steatosis (p<0.05). Apoptosis rate was similar in both groups. CONCLUSIONS Regeneration, but not apoptosis rate differs between micro- and macrovesicular steatosis. The reduced regenerative capacity in microvesicular steatosis may contribute to the worse prognosis of this subtype of fatty liver disease.
