Abstract
Safarimosavi, S, Mohebbi, H, and Rohani, H. High-intensity interval vs. continuous endurance training: Preventive effects on hormonal changes and physiological adaptations in prediabetes patients. J Strength Cond Res 35(3): 731–738, 2021—The aim of this study was to examine the effects of a 12-week high-intensity interval training (HIIT) intervention, or an isocaloric continuous endurance training (CET) intervention on insulin resistance indices and change in irisin and preptin in patients with prediabetes. Thirty-two prediabetic male patients (age = 38.7 ± 4; body mass index = 26.9 ± 1.4 kg·m−2; and V̇o
2peak = 2.49 ± 0.22 L·min−1) were randomly assigned into 3 training groups (N = 8). These groups were matched based on the required energy expenditure (EE) for completing each protocol: (a) HIIT (10 × 60 seconds at 90% peak oxygen uptake [V̇o
2peak], 1: 1 work to recovery at 50 W), (b) CET at an intensity equivalent to maximal fat oxidation (Fatmax) (CETFAT) (pedaling for a duration that expends an equivalent EE to an HIIT session [E ≈ HIIT]), (c) CET at an intensity equivalent to anaerobic threshold (CETAT) (E ≈ HIIT), and (d) the control group (CON): continued to perform their daily activities. After intervention, blood glucose levels were significantly (p < 0.05) lower in the HIIT group compared with CETAT group. Exercise training improved the insulin resistance index by 35, 28, and 37% in CETFAT, CETAT, and HIIT groups, respectively. Irisin concentrations in the HIIT and CETAT groups was significantly (p < 0.05) decreased compared with the pre-training values. Also, HIIT and CETFAT resulted in significant (p < 0.05) changes in preptin concentration compared with baseline. This study demonstrated that both HIIT and CETFAT protocols had similar effects on the insulin resistance index of prediabetic patients. Also, the intensity and type of exercise were effective factors in changing irisin and preptin concentrations.

Abstract
Robertson, C, Lodin-Sundström, A, O'Hara, J, King, R, Wainwright, B, and Barlow, M. Effects of pre-race apneas on 400-m freestyle swimming performance. J Strength Cond Res 34(3): 828–837, 2020—This study aimed to establish whether a series of 3 apneas before a 400-m freestyle time-trial affected swimming performance when compared with and combined with a warm-up. Nine (6 males and 3 females) regional to national standard swimmers completed four 400-m freestyle time-trials in 4 randomized conditions: without warm-up or apneas (CON), warm-up only (WU), apneas only (AP), and warm-up and apneas (WUAP). Time-trial performance was significantly improved after WUAP (275.79 ± 12.88 seconds) compared with CON (278.66 ± 13.31 seconds, p = 0.035) and AP (278.64 ± 4.10 seconds, p = 0.015). However, there were no significant differences between the WU (276.01 ± 13.52 seconds, p > 0.05) and other interventions. Spleen volume compared with baseline was significantly reduced after the apneas by a maximum of ∼45% in the WUAP and by ∼20% in WU. This study showed that the combination of a warm-up with apneas could significantly improve 400-m freestyle swim performance compared with a control and apnea intervention. Further investigation into whether long-term apnea training can enhance this response is justified.

Abstract

Background
Brain metastases (BM) from adult soft tissue or bone sarcomas are rare, and sparse data exist on their prognostic factors and management.

Subjects, Materials and Methods
A retrospective study was conducted in 15 centers of the French Sarcoma Group, plus one Canadian and one Swiss center, to report on clinical, histological, and treatment characteristics and to identify predictive factors of outcome.

Results
Between 1992 and 2012, 246 patients with a median age of 50 years (range: 16–86) were managed for BM. BM included 221 cerebral and cerebellar metastases and 40 cases of meningeal sarcomatosis. The most frequent histopathological subtype was leiomyosarcoma (18.7%). Histological grade was high in 118 (48%) cases. Surgery of BM was carried out for 38 (15.5%) patients. Radiotherapy and chemotherapy were administered in 168 (68.3%) and 91 (37.0%) patients, respectively. Irrespective of treatment modality, BM were controlled in 113 patients (45.9%), including 31 partial responses (12.6%) and 18 complete responses (7.3%). The median overall survival from diagnosis of brain metastasis was 2.7 months (range: 0–133). In the multivariate analysis, the following parameters influenced overall survival: chemotherapy (hazard ratio [HR] = 0.38; 95% confidence interval [CI]: 0.26–0.48), surgery (HR = 0.40; 95% CI: 0.22–0.72), stereotactic radiotherapy (HR = 0.41; 95% CI: 0.19–0.90), whole-brain radiotherapy (HR = 0.51; 95% CI: 0.35–0.76), and grade (HR = 0.65; 95% CI: 0.43–0.98).

Conclusion
BM of sarcomas are rare and associated with a dismal outcome. Multidisciplinary management with chemotherapy, radiation therapy, and surgery is associated with a better survival.

Implications for Practice
The incidence of brain and meningeal metastasis in bone and soft tissue sarcomas is estimated between 1% and 8%. Published data are derived from small retrospective case series, often in the pediatric population. A prognostic index is important to guide both clinical decision-making and outcomes research, but one such is lacking for adult sarcoma patients with brain metastases. The current study describes brain metastasis in a large cohort of sarcoma patients. This study, conducted within the French Sarcoma Group, describes the natural history of sarcoma brain metastasis and enables the proposal of strategic recommendations for subsequent clinical trials and for the management of such patients.

Published: June 2018

Introduction. The pathogenesis of Perthes disease is not fully understood and requires a greater understanding of the physical development, external and internal markers of connective tissue dysplasia.
Objective. To analyze the deviations in physical development and connective tissue dysplasia in children with Perthes disease to determine its phenotypes.
Materials and methods. We examined 52 patients and 36 children (control group) aged of 4–17 years. We estimated and compared their physical and proportional growth by using centile charts and Vervec’s index and defined external and internal manifestations of connective tissue dysplasia in major organs, systems, and topographic regions. Complete genealogical histories were taken by with examining the genealogies of 52 probands, including clinical examination of 136 first and second degree relatives.
Results. Deviations in physical growth were observed in 33 patients (63.5%). The body height of 27 (51.9%) patients aged 4–17 years ranged from 1–2 lines (3–10%) and was significantly lower than that of the control group within 5 lines (p < 0.5). Six (11.6%) children had body lengths higher than the average 7th line (75–90%). Vervec’s index in 34 (65.4%) children ranged from 1.25–0.85 and represented mesomorphy, moderate brachy, or dolichomorphia. The primary pathology of external organs and systems was skeletal anomalies in 36 (69.2%) children, followed by dermal in 23 (44.2%) and organs of vision in 9 (17.3%). Among visceral disorders, the primary pathology was cardiovascular diseases in 17 (32,7%) children followed by surgical and urological pathologies in 7 (13.5%) and digestive system disorders in 5 (9.6%). Disease inheritance was sporadical in 48 (92.3%) children.
Conclusion. The Perthes disease phenotype was related to the undifferentiated form of collagenopathies.

Authors: Barik Kanai Lal , Paul Uttam Kumar 
Published: June 2018

Background: Breastfeeding is the easiest, cost effective and most successful intervention and the most effective life-saving interventions for the health of the newborn. In spite of profound beneficial effects of breast milk, breastfeeding rates in India are abnormally low. There is lack of qualitative data regarding breastfeeding in India. So, we have planned to assess the perceptions of first time mothers about breastfeeding at this middle part of Bengal.Methods: The study was conducted in the Pediatric department of Burdwan Medical College, Burdwan, West Bengal. The study was one of qualitative descriptive types involving in depth interviews (IDI) of 21 first time mothers. The interviews were translated into English transcripts which were then analysed to find out suitable codes and categories.Results: The results of the in-depth interviews of the 21 first time mothers could be divided into seven categories and each of which is further divided into several codes. The categories are: Reaction of mother, inadequate breast milk, breast milk causing ailments of the baby, erroneous idea about breastfeeding, lack of time, lack of privacy and breast milk is best for my baby.Conclusions: In this present study we have applied qualitative in-depth interview approach and able to find out different reasons of non-continuation of breastfeeding among the first-time mothers. Though they have to face challenges regarding continuation of breastfeeding but most of them felt that breastfeeding is best for their baby.

Published: June 2018

Aim: Beside efficacy of the shock wave
lithotripsy (SWL) procedure, also its negative effects on the kidneys, its relation
with the oxidant/antioxidant balance and the search after biomarkers for the
detection of this negative effect gained interest in the recent years. The aim
of the study is to investigate the possible usage of total antioxidant status (TAS), total oxidant
status (TOS), oxidative stress index (OSI), Paraoxonase-1 (PON-1) and Interleukin 6 (IL-6) parameters
as biomarkers for renal injury/trauma in
the early period by patients undergoing SWL due to kidney stones.

Material
and Methods: Forty patients receiving SWL therapy due to kidney stones were
included to study by collecting their blood samples
before and 2 hours after the procedure.

Results: It was observed that SWL therapy has
deteriorated the oxidant/antioxidant balance in terms of the oxidants by analyzing
the increase of IL-6 (P &lt;0,01) and
decrease in PON-1 (P = 0.049). There
was no change observed in TAS (P =
0.178) and TOS (P = 0.175) and OSI (P = 0.551) parameters.

Conclusion:
This has shown
that IL-6 and PON-1 may be more sensitive markers of renal injury after SWL in
early period.
Evaluation of the Breakdown Pressure to Initiate Hydraulic Fractures of Tight Sandstone and Shale Formations
Authors: Farid Ibrahim Ahmed , Nasr-El-Din Hisham 
Published: June 2018

Abstract
Hydraulic Fracturing has been used successfully in the oil and gas industry to enhance oil and gas production. Recent years have seen the great development of tight gas, coalbed methane, and shale gas. Different fluids were used as fracturing fluids in shale and sandstone formations, including the use of CO2, N2 and CO2 foam, slick water, crosslinked solutions, and oil-based fracturing fluids. The objective of this study is to develop an experimental setup to measure the breakdown pressure to initiate the fractures in shale and tight sandstone cores.
This study investigated the effect of injection flow rate, temperature, fluid viscosity, and fluid type on the breakdown pressure of different rock cores. 5 wt% KCl brine, slick water with a friction reducer, linear gel systems were used as a fracturing fluid. Kentucky, Scioto, Bandera, and Berea sandstone cores were used. Also, Mancos, Marcellus, and Barnett shale cores were used in this study. Finally, the behavior of the breakdown pressure was examined as a function of the back pressure (0, 100, 300 psi).
The preliminary results show that the breakdown pressure increased as the injection flow rate increased. Where the breakdown pressure increased from 438 to 1,000 psi as the flow rate increased from 5 to 10 cm3/min in case of 5 wt% KCl with Kentucky sandstone cores. The breakdown pressure increased in Marcellus shale to 1,800 psi in case of 5 wt% KCl at 5 cm3/min. As the fluid viscosity increased the breakdown pressure increased, it increased to 1,115 psi in case of 2 gptg friction reducer (5 cp) comparing to 5 wt% KCl (1.1 cp) case at 5 cm3/min. A straight line relationship was found between the breakdown pressure and the logarithmic scale of the fluid viscosity.
This study will give recommendations for the fluid viscosity, type, and the injection flow rate that will improve the efficiency of the hydraulic fracturing operation.

Experimental investigation of the effect of temperature differentials on hydraulic performance and flow pattern of a sediment retention pond
Authors: Hendi Ehsan , Shamseldin Asaad Y. , Melville Bruce W. , Norris Stuart E. 
Published: June 2018

Abstract
Existing studies on sediment retention ponds (SRPs) have examined the effects of pond layout, inlet and outlet geometry and the installation of baffles on the performance of the SRPs. However, the effects of a temperature difference between the ambient water in the pond and the inflow are often neglected, and the buoyancy forces arising from these differences in temperature can potentially change the flow in the pond and hence its hydraulic performance. This study has experimentally evaluated the effect of these temperature differences on the flow field and residence time in a retention pond for a range of temperature differences. As expected a cold inflow sinks to the bottom of the pond while a hot inflow remains at the surface, but in both cases the inflow flows more rapidly towards the outlet than is the case for isothermal inflow. A counter-current was observed at the bottom or the surface of the pond for colder or hotter influents, respectively. These thermally induced flows significantly reduced the residence time of the pond, reducing the hydraulic performance of the pond and causing severe short-circuiting. The results have also shown that the temperature differences in the pond decrease with time, yet small temperature differences persist with the pond remaining thermally stratified.
Sonocatalyzed Total Synthesis of N,N-diaryl-formamides Through Oxidation and Hydrolysis Reaction of gem-dichloroaziridines using DMSO/H2O
Authors: Rabiei Khadijeh , Naeimi Hossein 
Published: June 2018

Background:.Aziridine compounds are among the most fascinating intermediates in organic synthesis,
acting as precursors of many complex molecules due to the strain incorporated in their skeletons and can
be opened in a stereo controlled manner with various nucleophiles, providing access to a wide range of important
nitrogen-containing products. Sonochemistry involves the use of ultrasound technique to promote organic
reactions. In recent years sonochemistry has been widely used in organic syntheses as it offers a versatile and
facile pathway for a bewildering range of organic reactions.

Materials and Method:
The synthesis of some Schiff bases was done in according the previously reported procedure
in literature. The synthesized Schiff bases in the presence of magnesium powder and CCl4 in anhydrous
tetrahydrofuran was converted to gem-dichloroaziridines at ultrasonic irradiation. Finally, the synthesized 2,2-
dichloro-1,3-bis(4-chlorophenyl) aziridine was treated with DMSO and H2O with ultrasonic irradiation to produce
the N-(4-chlorophenyl)-N-[4-(chlorophenyl)hydroxy-methyl] formamides.

Results:
Here, total synthesis of N-(α-hydroxybenzyl)-formamides through ultrasonic promoted oxidation and
hydrolysis reaction of gem-dichloroaziridine derivatives in the presence of dimethyl sulfoxide and water has
been investigated.

Conclusion:
In this study, ultrasonic promoted oxidation and hydrolysis of gem-dichloroaziridines toward N-
(α-hydroxybenzyl)-formamides in the presence of DMSO and H2O under neutral medium reaction conditions
has been reported. Excellent yields of products were obtained through this method. Other advantages of this
reaction are short reaction times, simplicity of the method and high purity of products.
