Continuous progeny testing, use and selection of proven bulls in Israel
The breeding policy of the Israeli Holstein-type dairy cattle is reviewed. The bulls are progeny tested on their daughtersâ first three lactations. The traits evaluated are the following: milk, fat, yield persistency, fertility, incidence of mastitis, and % cullings for three most important reasons. The test analysis takes into account the genetic level of daughtersâ contemporaries and maternal grandsires. The paper describes a general outline of the selection decisions in AI bulls. Considerable amount of imported semen is used for breeding young bulls. Breeding goals are discussed against the estimated genetic parameters for and between the given traits

Species of Mycosphaerella and related anamorphs on Eucalyptus leaves from Thailand
Species of Mycosphaerella and their related anamorphs represent potentially serious foliar pathogens of Eucalyptus. The fungi treated in the present study were isolated from symptomatic Eucalyptus leaves collected in Thailand during JuneâOctober 2007. Species were initially identified based on morphological and cultural characteristics. Identifications were confirmed using comparisons of DNA sequence data of the internal transcribed spacers (ITS1, 5.8S nrDNA, ITS2) and the 28S nrDNA (LSU) regions. To help distinguish species of Pseudocercospora, the dataset was expanded by generating partial sequences of the translation elongation factor 1-α and actin genes. By integrating the morphological and molecular datasets, five new taxa were distinguished, namely Mycosphaerella irregulari, M. pseudomarksii, M. quasiparkii, Penidiella eucalypti and Pseudocercospora chiangmaiensis, while M. vietnamensis represents a new record for Thailand
Enhancing the Stretchability of Two-Dimensional Materials through Kirigami: A Molecular Dynamics Study on Tungsten Disulfide
In recent years, the 'kirigami' technique has gained significant attention
for creating meta-structures and meta-materials with exceptional
characteristics, such as unprecedented stretchability. These properties, not
typically inherent in the original materials or structures, present new
opportunities for applications in stretchable electronics and photovoltaics.
However, despite its scientific and practical significance, the application of
kirigami patterning on a monolayer of tungsten disulfide (WS2), a van der Waals
material with exceptional mechanical, electronic, and optical properties, has
remained unexplored. This study utilizes molecular dynamics (MD) simulations to
investigate the mechanical properties of monolayer WS2 with rectangular
kirigami cuts. We find that, under tensile loading, the WS2 based kirigami
structure exhibits a notable increase in tensile strain and a decrease in
strength, thus demonstrating the effectiveness of the kirigami cutting
technique in enhancing the stretchability of monolayer WS2. Additionally,
increasing the overlap ratio enhances the stretchability of the structure,
allowing for tailored high strength or high strain requirements. Furthermore,
our observations reveal that increasing the density of cuts and reducing the
length-to-width ratio of the kirigami nanosheet further improve the fracture
strain, thereby enhancing the overall stretchability of the proposed kirigami
patterned structure of WS2.Comment: 19 pages, 5 figure
Assessment of the inhalation technique and adherence to therapy and their effect on disease control in outpatients with asthma
Objectives The objective of this study was to assess correct use of inhaler devices,
adherence to inhaler corticosteroid treatment and their effects on asthma control.
Methods This study was a prospective, single-centre, observational study conducted
between July and February 2016 at Al-Makased Hospital, respiratory outpatient clinic.
Inhaler technique of asthma patients using pressurized metered-dose inhalers or dry powder
inhalers (Turbuhaler (TH) and Accuhaler DiskusTM (ACC)) were assessed against
published inhaler technique checklists. Asthma control variables measured using Asthma
Control Test (maximum 25, higher score corresponding to better asthma control) were
assessed, and adherence to asthma medications was assessed by Morisky adherence scale.
Key findings Two hundred and twenty patients were recruited in the study. The mean
age was 42.3 15.2 years and 59.1% were male. One hundred and seventeen (53.2%)
were using TH, 60 (27.3%) were using ACC and 43(19.5%) were using MDIs. Only 22
(10%) were smoker and only 48 (21.8%) patients were their asthma controlled (ACT
score >20). The devices were used correctly by 79.1% of patients using MDI, 69% of
ACC and 55.6% of TH users (P > 0.001). The most common improper step was âforceful
inhalationâ (65.4%) made by the MDI users, âNot exhaling to residual volumeâ (58.7%)
made by ACC users and âNot inhaling deeply enoughâ (52.2%) made by TH users. Multivariate
analysis showed that the likelihood of having controlled asthma was significantly
higher in those with correct inhaler techniques (OR 2.3; 95% CI: 1.08â4.77; P = 0.028),
high adherence to medications (OR 2.37; 95% CI: 1.05â4.92; P = 0.03) and having a
higher level of education (OR 2.58; 95% CI: 1.19â3.63; P = 0.018).
Conclusions It was found that asthma control was better among correct users. Repetitive
training about using devices may contribute improving inhaler technique.This research received no specific grant from any funding

Pharmacistsâ Knowledge, Attitudes and Practices Towards Herbal Remedies In West Bank, Palestine
Background:
There is an increasing trend towards consumption of
complementary and alternative herbal products in many parts of the
world.
Objectives:
The purpose of this study was to investigate the knowled
-
ge and attitudes among pharmacists in West Bank, Palestine towards
the use of herbs.
Methods:
Self-administered questionnaire was designed as the study
instrument and distributed among 350 qualified pharmacists working
in government and private pharmacies in West Bank, Palestine.
Results:
The response rate was 82.9% (290/350). The mean age of
the pharmacists was 32.9 (SD=6.5) years. The majority of the phar

macist 238 (82.1%) worked in the community pharmacies and their
experience in practice ranged from 1 to 26 years. Product package
instructions and product representative were the most consulted by
the pharmacists (128; 44.2% and 73; 25.2% respectively). General
health tonic preparations were the most widely dispensed drugs (142;
48.9%), followed by cough preparations (55; 19.0%) and slimming
agents (64; 22.1%). The Majority of pharmacists (195; 67.2%) belie

ved herbal remedies were effective; however, about fifty percent of
the pharmacists had concern about their safety. The knowledge of
respondents about the indications of herbal medicine was good, but
their awareness of interactions, contraindications and adverse effects
was inadequate. The majority of Pharmacists (255; 87.9%) believed
that herbal product should undergo increased regulation and (215;
74.9%) believed that information available about herbal and natural
product isn't adequate
Pharmaceutical care for adult asthma patients: A controlled intervention oneâyear followâup study
Asthma is a clinical problem with social, psychological and economic burdens. To
improve patient disease management, different education programmes have been
developed. Challenges in asthma management may be partially attributed to nonadherence
or improper use of inhalers. This study aimed to implement and assess
hospitalâbased pharmaceutical care services for asthmatic patients. A 12âmonth, singleâ
centre, randomized, controlled study was initiated in asthmatic adult patients who
had been divided into either a control or intervention group. Patients in the control
group received the usual care, and patients in the intervention group received patient
counselling per study protocol that covered asthma knowledge, control, adherence to
treatment and inhalation techniques. The main variables compared measurements at
baseline with those at 6 and 12 months. A total of 192 patients completed the study
protocol: 90 in the control group and 102 in the intervention group. The control
group included 90 patients, and the intervention group included 102 patients. Over
the course of the 12âmonth followâup period, a significant difference was observed
between intervention and control groups with respect to asthma control (38.2%
vs 10.0%; P < .001), mean correct inhalation technique (confidence interval [CI]:
8.1, 7.8â8.5 vs CI: 6.1; 5.6â6.6; P = .01) and good medication adherence (60.7% vs
50.0%, P = .02). There were 34% and 25% decreases in emergency room visits and
hospital admissions, respectively, in the intervention group compared to the control
group. This study emphasizes the importance of patient counselling in asthma management
and the significant contribution that the pharmacist's intervention can have
on asthma control
