Abstract The analysis of slaughter yield and meat quality was performed on a total number of 96 birds from four medium-heavy weight pedigree strains. Based on their strain, cockerels were divided into the following groups: group I - strain N88 (originating from New Hampshire), group II - strain R55 (Rhode Island Red), group III - strain S11 (Sussex) and group IV - strain P55 (Plymouth Rock). Each group consisted of 24 birds. At 12 weeks of age, half of the cockerels from each group was caponised. In total, 48 birds were caponised (12 birds in each strain). Based on the strain, capons were then divided into groups V (N88), VI (R55), VII (S11) and VIII (P55). It was noted that the strain and caponisation had influence on differences in such traits as the weight of eviscerated carcass with neck and slaughter yield. On the other hand, it was observed that caponisation did not affect significantly the total weight, percentage share of breast and drumstick muscles in carcasses of birds from analysed strains. No significant differences were observed between groups in terms of physicochemical properties of meat. The highest content of water in breast and drumstick muscles was observed among cockerels and capons from strain N88 (groups I and V). Protein content in cockerels’ breast muscles differed depending on their strain whilst among capons (groups V-VIII) it was similar. It was also noted that capons originating from strains S11 (VII) and P55 (VIII) stood out significantly with higher fat content in breast muscles compared to cockerels from the same strain (groups III and IV). The effect of caponisation on higher fat content in drumstick muscles was confirmed in all observed groups. Capons from all strains had more fat in drumstick muscles compared to cockerels of the same origin.

A Prospective Study

Abstract We previously suggested that a reinfused threshold dose of CD34+38− cells = 5x104/kg b.w. better predict both short- and long-term engraftment after PBSCT than total CD34+ cells assessment, and should thus avoid unecessary postransplant (Tx) G-CSF administration. Therefore, we have further conducted a prospective study comparing postTx data from cancer patients undergoing autologous PBSCT and were administered or not G-CSF depending on the amount of CD34+38− cells reinfused. 48 patients (mean age 49y) were transplanted with, on average 2.5x104 CD34+38− cells/kg b.w. (range 1–49) and were consequently administered G-CSF 5 μg/kg daily from d5 to ANC = 109/1 (Group-I). 46 patients (mean age 50y) received an average of 20.5x104 CD34+38− cells/kg (range 5.5–162) without postTx G-CSF (Group-II). These 2 groups were compared and paired two by two with 2 groups of "historical" patients referred as controls : 11 patients (mean age 44y) had received, on average, 2.5x104 CD34+38− cells/kg b.w. (range 1.1–4.8) without G-CSF (Group-III); 29 patients (mean age 51y) received an average of 15.2x5x104 CD34+38− cells/kg b.w. (range 5.5–60) systematically associated with G-CSF for protocolar reasons (Group-IV). PostTx trilineage hematopoietic engraftment (up to 2 years), clinical and economical parameters were systematically recorded for each group of patients and statistically compared. PostTx ANC recovery occurred sooner, was faster and reached higher levels in the G-CSF groups (II and IV) compared to the others; platelets recovery kinetics was significantly faster in Group-III compared to the others; reticulocytic recovery was not statistically different whichever the group. When age, sex, disease, TBI did not significantly influence trilineage engraftment, a multiparametric study showed strong positive impacts of total CD34+ cells reinfused on ANC kinetics and of CD38− subset amounts on platelet kinetics, which was on the contrary slowered by G-CSF administration. Group-I patients received more transfusions, stayed longer hospitalized and costed more than those of the 3 other groups. Regarding long-term hematopoiesis, platelets and hemoglobin levels were globally higher in Group-III compared to the other groups, but still more dramatically compared to Group-IV from 1 to 9 months, which might be explained by differences in BM CD34+ and 38− subset differentiation. In conclusion, if postTx G-CSF certainly accelerates ANC recovery, it seems to be to the detriment of short- an d median-term platelets and hemoglobin recovery, even in case of reinjection of CD34+38− cell doses = 5x104/kg b.w., which appears thus to be significantly discriminant for G-CSF administration decision.

One-hundred and twenty-one isolates of Salmonella enterica serotype Montevideo, representing different biotypes and incidents of infection detected in the UK between 1977 and 1995, were analysed by EcoRI ribotyping, PvuII ribotyping and IS200 fingerprinting. Among the isolates examined, 7 EcoRI ribotypes, 5 PvuII ribotypes and 55 IS200 profile types were recognized and 4 arbitrary groups defined. All 33 isolates of biotype 2d belonged to EcoRI/PvuII ribotype 1/1 and IS200 lineage A and comprised Group I. The other 88 isolates of biotype 10di and its variants were assigned to Groups II–IV. All 27 isolates in Group II were of EcoRI/PvuII ribotype 2/2 and IS200 lineage B. Among the 43 isolates in Group III, 42 of which were of EcoRI/PvuII ribotype 3/3, IS200 analysis identified 38 profiles in lineages C–I. Six EcoRI/PvuII ribotypes and 8 IS200 profiles, mostly in lineages C–E, were recognized among the 18 isolates in Group IV. The combined use of biotyping and ribotyping, and to some extent IS200 profiling, has enhanced our understanding of the clonal structure of serotype Montevideo and provides a basis for further study.

<p><strong>OBJECTIVE:</strong> Despite the availability of better biomarkers, basal day 3 follicle-stimulating hormone is widely available and often used as the first-line test in ovarian reserve evaluation. The aim of this study was to evaluate the outcomes of cycles with elevated (&gt;12 IU/mL) basal follicle-stimulating hormone values. </p><p><strong>STUDY DESIGN:</strong> Cycles with basal day 3 follicle-stimulating hormone values &gt;12 IU/mL were divided into four cohorts according to follicle-stimulating hormone levels: group I, follicle-stimulating hormone between 12-15 IU/m, group II between 15-20 IU/mL, group III between 20-25 IU/mL and group IV &gt;25 IU/mL. Both demographic characteristics and controlled ovarian stimulation parameters were retrospectively reviewed. </p><p><strong>RESULTS:</strong> Total antral follicle count was significantly higher in group I compared to the other three groups (p=0.001). Number of follicles ≥17 mm on human chorionic gonadotropin (hCG) day, number of retrieved oocytes, mature oocytes and fertilized oocytes were significantly higher in group I compared to the other groups (p=0.003, p=0.001, p=0.001, and p=0.001, respectively). No significant difference was found between groups regarding cancellation rates. The rate of embryo transfer per started cycle was significantly higher in group I compared to group III and group IV (p=0.001). Clinical pregnancy rates per embryo transfer were comparable among the groups.</p><p><strong>CONCLUSION:</strong> Despite the retrieval of lower quantities of oocytes, reasonable pregnancy rates could be achieved if embryo transfer was performed in cycles with follicle-stimulating hormone values over 12 IU/mL.</p>

BACKGROUND: The increased strength of zirconia has resulted in its widespread application in clinical dentistry. Nevertheless, the fracture of veneering porcelains remains one of the key reasons of failure. OBJECTIVE: The objective of this study was to compare and analyze the influence of surface conditioning methods on the core-veneer bond strength of zirconia restorations. METHODS: Thirty specimens of zirconia core with sizes 10 × 5 × 5 mm were layered with porcelain of sizes 5 × 3 × 3 mm. On the basis of different surface conditioning methods, four groups were made: Group I: abrasion with airborne alumina particles of 110 μm size, Group II: sandblasting with silica coated alumina particles of 50 μm in size, Group III (modified group): alteration with a coating of zirconia powder prior to sintering, and Group IV (control group): metal core specimens. The shear force of all specimens was tested using a universal testing machine with a 0.5 mm/min crosshead speed. One-way analysis of variance (ANOVA) and Tukey’s post hoc pair wise comparison (p= 0.05) were performed to analyze the shear bond strength. A scanning electron microscope was used to assess the fractured specimens. RESULTS: A statistically significant difference was noted between the groups. The mean value of shear bond strength was 40.25 MPa for Group I, 41.93 MPa for Group II, 48.08 MPa for Group III and 47.01 MPa for Group IV. CONCLUSIONS: The modified zirconia group and control group demonstrated a significantly higher mean bond strength than that of Group I, where airborne particle abrasion was used. The scanning electron microscope showed that cohesive fracture in the porcelain veneers was the main problem of failure in altered zirconia. The modified zirconia specimens in Group III demonstrated significantly improved values of shear bond strength.

The Difference

The monthly wool growth of three groups of rams was studied at Beltsville, Maryland. Group I received natural daylight (at 38° 53' N.) and was shorn monthly. Group II had a 7:17 hours of daylight to hours of darkness rhythm and was shorn every 6 months, once in winter and once in summer. Group III received natural daylight and was likewise shorn every 6 months. The rams of all groups produced more wool in summer than in winter. This difference was significant (P<0.001). The mean body weight and food intake were both greater in the winter months, which indicated that the seasonal rhythm of wool growth was not a consequence of poorer feeding in winter. The rams which were shorn monthly (group I) grew considerably more wool than the other two groups, but the difference was not statistically significant. The short-day treatment of group II did not increase the annual wool production nor decrease the seasonal rhythm of wool growth. The balance of evidence from this and other experiments indicates that temperature rather than light controls the seasonal rhythm of wool growth.

AbstractRecent years have seen a rising incidence of male infertility, mostly caused by the decline of sperm quality. The ratio of infertile males to infertile females has escalated from 3:7 in 2013 to current 5:5, which turns male infertility into the research focus of reproductive medicine. This study aimed to clarify the effect of reproductive tract infection by ureaplasma urealyticum (UU) and chlamydia trachomatis (CT) on the DNA integrity and routine semen parameters of infertile males. A retrospective study was performed. A total of 259 infertile males who were treated at the Andrological Laboratory Examination and Reproductive Medicine Center in our hospital were analyzed. qRT-PCR was used to examine the infection status of CT and UU. According to the eligibility criteria, we evaluated the semen parameters and biochemical data of 253 men. Based on the results of PCR, the subjects were divided into four groups: Group I (CT positive, 63 cases), Group II (UU positive, 60 cases), Group III (CT positive and UU positive, 62 cases), and Group IV (no infection, 68 cases). DNA fragmentation index (DFI), sperm count, vitality and morphology, elastase level, seminal plasma malondialdehyde (MDA), and total antioxidant capacity (TAC) were assessed. Compared to Group IV, three groups (Group I, Group II and Group III) showed difference in semen volume, proportion of sperm with normal morphology, sperm motility, progressive motility, and vitality (P < 0.05). Compared to Group IV, Group II and Group III showed difference in DFI (P < 0.05). Compared to Group IV, Group II and Group III showed difference in elastase level (P < 0.05). VCL, VSL, VAP, WOB, ROS, TM, HDS showed differences between groups of abnormal/normal WBC (*P < 0.01).UU infection significantly increased the level of seminal leukocytes only in Group II, but not in the other three groups, indicating that UU is a factor to increase the level of seminal leukocytes. Compared with the normal leukocyte group, there were significant differences in total motility, forward motility and normal sperm ratio between the two groups. The proportion of sperm with abnormal morphology (mostly in the head) showed obvious difference between groups of high and normal seminal leukocytic levels. At the same time, in this study, SCGE and SCD verified that leukocytes could damage sperm DNA by increasing ROS, which ultimately affects male fertility.

Rapid Correction

The purpose of the present studies was to examine the effects of rapid correction of severe hyponatremia (serum sodium less than 120 meq/liter) either to mildly hyponatremic levels (serum sodium = 130 meq/liter) or to normonatremic levels (serum sodium = 150 meq/liter) on the brain histology of rats. In group I, 13% of the rats revealed brain lesions following correction to mildly hyponatremic levels by the administration of 855 mM NaCl. All the rats (100%) in group II had brain lesions following correction to normonatremic levels by 24 h of water restriction. Similarly, all the rats in group III showed brain lesions following correction to normonatremic levels by the administration of 855 mM NaCl. Severe hyponatremia by itself did not cause any brain lesions in another group. We conclude that rapid correction of severe hyponatremia to mildly hyponatremic levels by the administration of 855 mM NaCl does not cause significant brain lesions. On the other hand, rapid correction to normonatremic levels either by water restriction or by the administration of 855 mM NaCl results in significant brain lesions.

The 24-hour urinary excretion of coproporphyrin was measured in three groups of children. Group I consisted of 88 children with acute scarlet fever, hospitalized in Providence, Rhode Island, during an epidemic in the spring of 1957. Single 24-hour specimens of urine were obtained during the first or second week of illness. Group II was composed of 54 children with sporadic streptococcal pharyngitis seen by private pediatricians in Atlanta, Georgia. Urinary excretions of coproporphyrin were measured during the acute illness and at weekly intervals thereafter. Group III included 21 children with nonstreptococcal pharyngitis. Acute streptococcal infection usually is not associated with a significantly increased rate of urinary excretion of coproporphyrin in children who do not develop subsequent acute rheumatic fever. A greater rate of urinary excretion of coproporphyrin by boys than by girls was significant at the 1% level of confidence.

Pyrethroid cyhalothrin (PC) is an insecticide that is used worldwide for pest control in agriculture and household use. Samoa extract (SE) is a potent antioxidant protecting cells from oxidative stress. The present study investigates the protective and therapeutic effect of SE on PC-induced changes in sperm quality in male rats. Fifty adult male albino rats were divided into five groups: group I: served as control; group II: received PC i.p. only (6.2 mg/kg b.wt.); group III: received SE only (100 mg/kg b.wt., p.o.) for eight weeks; group IV: received SE as a protective agent daily for eight weeks, then followed by the administration of PC (i.p.) three times a week for two weeks; group V: exposed to PC (i.p.) three times a week for two weeks, then treated with the SE daily for 8 weeks. Results showed that PC caused markedly impaired sperm quality (a count, viability, motility, and abnormality). Compared to PC-treated animals, SE in the protective group markedly restored the alteration of sperm indices. However, SE in the curative group was found to be less effective in restoring PC-induced alterations. In conclusion, the data of this study revealed that the SE as a protective agent is more effective than as a therapeutic agent. Keywords: Samoa; Pyrethroid; Sperm quality; Rat

We evaluated the dose-response relationship between the plasma amino acid (AA) concentration and renal hemodynamics in eight normal subjects. After an overnight fast, a balanced 10% AA solution was infused for 180 min at five separate infusion rates: 0.5 (group I), 1.0 (group II), 2.0 (group III), 4.0 (group IV), and 6.0 (group V) ml.kg-1.min-1 on separate days. Basal plasma AA concentration was 1.87 +/- 0.1 mmol/l and increased to 2.26 +/- 0.1 (group I), 2.66 +/- 0.2 (group II), 3.79 +/- 0.5 (group III), 5.81 +/- 0.4 (group IV), and 7.41 +/- 0.4 mmol/l (group V). Basal glomerular filtration rate (GFR) and renal plasma flow (RPF) averaged 95 +/- 4 and 476 +/- 29 ml.1.73 m-2.min-1, respectively, and rose to 98 +/- 5 and 506 +/- 40 (group I) [P = not significant (NS)], 102 +/- 3 and 533 +/- 30 (group II) (P < 0.05 vs. basal), 110 +/- 4 and 567 +/- 29 (group III), 115 +/- 7 and 610 +/- 55 (group IV), and 117 +/- 7 and 614 +/- 66 ml.1.73 m-2.min-1 (group V) (P = NS vs. group IV). Basal plasma glucagon concentration averaged 68 +/- 10 pg/ml and increased to 74 +/- 10 (group I), 83 +/- 11 (group II) (P < 0.05 vs. basal), 100 +/- 14 (group III), 121 +/- 14 (group IV), and 229 +/- 35 pg/ml (group V) (P < 0.01 vs. basal). Increases in plasma growth hormone (GH) and insulin levels were observed only during groups IV and V.(ABSTRACT TRUNCATED AT 250 WORDS)
