I Regret as My Family Fallows My Entrepreneurial Self-Efficacy! Evidence from the Male Sample of an Emerging Economy (Pakistan)
Authors: Ahmed Ishfaq , Islam Talat 
Published: August 2021

AbstractEntrepreneurial activities require thoughtful and cumbersome efforts, positive and forward-looking upward spiral, and strong entrepreneurial intentions. Drawing from the work-family interface model, this study aims at investigating the impact of entrepreneurial self-efficacy (ESE) on venturing intentions through moderated mediation mechanisms of family support and regret. The data were collected from 335 male graduate students of business schools through questionnaires from public sector universities of Pakistan in two lags, because the participation of the labor force in Pakistan is primarily influenced by the demographical composition (i.e., Males), which is linked with cultural traits of the nation. The study used Hayes Macros to test the hypotheses. The findings of the study reveal that ESE positively influences intentions, while low family support reduces the effects of ESE. Low family support also increases the regret of not starting a business for those individuals who had high self-efficacy. A Moderated-mediation mechanism also exists among the variables of the interest. This study reports the effects of low family support and regrets on intentions in the short-run (i.e., four months interval), future studies should conduct longitudinal studies to understand the long-term relationship. Increasing unemployment in developing countries requires unique and timely solutions and entrepreneurship is the most viable one. But this study highlights an important considerations of family support while making policy decisions. The findings highlight that mere entrepreneurial self-efficacy is not enough, and due to collectivist culture the family norms have great impact on the entrepreneurial choices and intentions. This study examines the mechanism between ESE and entrepreneurial intentions considering anticipated regret as a mediating variable and family support as a conditional variable. This study is first of its kind that has linked family support, ESE, regret, and entrepreneurial intentions using the work-family interface. It explains how family support can enhance regret and the relationship between self-efficacy and intentions.

Published: August 2021

Abstract

Objectives
This study examines the effect of hypnotherapy on exam anxiety among first-year nursing students. Nursing students have high tendency to experience stress and anxiety. Anxiety therapy which encompasses mind and body would be helpful for them.

Methods
Sixty first-year nursing students participated in this interventional study. The hypnotherapy sessions started eight weeks prior to second exam. Outcome of hypnotherapy were assessed by measuring the exam anxiety score using TAI and clinical measurements (serum cortisol and vital signs). The measurements were done twice, there are two exams, where first exam and measurement were 1 day before exam (without hypnotherapy) and the second exam and measurement were 1 day before exam (with hypnotherapy).

Results
The mean difference of exam anxiety score and serum cortisol level between pre and post hypnotherapy sessions was statistically significant.

Conclusions
This study found that hypnotherapy is an effective tool in the management of exam anxiety among the nursing students.

Published: August 2021

Abstract

Objectives
The accumulation of genetic damages in onset of cancer induce activation of protooncogenes or inactivation of tumor suppressor genes thus cause disruption of the balance between cell proliferation and programmed cell death. As a member of the apoptosis inhibitory protein family (IAP), survivin play important roles in carcinogenesis process. The evidence suggests that polymorphisms located in survivin promoter region may be important in determining genetic susceptibility of cancer. In this study, we aimed to examine a possible role of survivin −31 and −625 G/C gene polymorphisms in breast cancer.

Methods
A total of 160 breast cancer cases and 153 healthy controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodology.

Results
Genotype and allele distributions and of −31 and −625 G/C polymorphisms were not significantly different between two groups. However, we observed the carriers of survivin −625 C/G polymorphism homozygous genotypes (GG/CC) were the significantly higher in patients with tumor necrosis (p=0.047).

Conclusions
Our results suggest that survivin −625 C/G polymorphism may be related with tumor prognosis, but we are opinion of that our result require to be validated in larger samples and further comprehensive research may explore the correlation.

Abstract
High-temperature X-ray diffraction (XRD) experiments up to T = 2710 °C have been performed on ZrSiO4 and ZrO2 powders, using the container-less levitation technique. A two-dimensional imaging plate (IP) detector was used for short-time observation. The diffraction data in a wide area was projected in one dimension. The unit cell parameters, thermal expansions, and c/a ratios for ZrSiO4 (space group I41/amd and Z = 4), tetragonal ZrO2 (space group P42/nmc and Z = 2) and cubic ZrO2 (space group

and Z = 4) were measured to understand the high-temperature behaviors. The transition temperature between tetragonal and cubic ZrO2 was specified to be between 2430 and 2540 °C. The pre-transitional behavior was observed around 2200 °C. As no clear change in unit cell volume is evident, the phase boundary between the tetragonal and the cubic phase has been shown to be a positive slope. The ZrO2 and ZrO2–SiO2 phase diagrams are proposed based on the chemical composition and the crystal structure.

Published: August 2021

Abstract
This article studies the microstructure and mechanical properties of diamond-like carbon films (α-C), depending on their architecture. The bilayer (titanium/a-C) and (titanium nitride [TiN]/a-C) films were deposited from the flows of the metal plasma, formed through sputtering a titanium cathode by a direct current arc, and the carbon plasma, formed as a result of pulsed arc sputtering of a graphite cathode. The effect of titanium and TiN sublayers on the structure and mechanical properties of carbon films has been shown. It has been found that the catalytic effect of the sublayer is most pronounced when the carbon layer thickness is less than 90 nm; when the carbon layer thickness is less than 30 nm, the size of Csp2 clusters decreases, and the fraction of atoms with Csp3 bonds increases. The annealing of the films does not significantly affect the behavior of the phase composition and the structure of the films with an increase in the carbon layer thickness. It has been demonstrated that the size dependences of the optical properties, which are manifested in a transparency increase and a change in the band gap when increasing the carbon layer thickness, are associated with the occurrence of mutual diffusion processes in the interfacial zone.
Savings in Human Force Field Learning Supported by Feedback Adaptation
Authors: Mathew James , Lefèvre Philippe , Crevecoeur Frederic 
Published: August 2021

AbstractSavings have been described as the ability of healthy humans to relearn a previously acquired motor skill faster than the first time, which in the context of motor adaptation suggests that the learning rate in the brain could be adjusted when a perturbation is recognized. Alternatively, it has been argued that apparent savings were the consequence of a distinct process that instead of reflecting a change in the learning rate, revealed an explicit re-aiming strategy. Based on recent evidence that feedback adaptation may be central to both planning and control, we hypothesized that this component could genuinely accelerate relearning in human adaptation to force fields (FFs) during reaching. Consistent with our hypothesis, we observed that on re-exposure to a previously learned FF, the very first movement performed by healthy volunteers in the relearning context was better adapted to the external disturbance, and this occurred without any anticipation or cognitive strategy because the relearning session was started unexpectedly. We conclude that feedback adaptation is a medium by which the nervous system can genuinely accelerate learning across movements.

Published: August 2021

AbstractStriatal activity is necessary to initiate and execute sequences of actions. The main excitatory input to the striatum comes from the cortex. While it is hypothesized that motor and premotor cortico-striatal projections are important to guide striatal activity during the execution of sequences of actions, technical limitations have made this challenging to address. Here, we implemented a task in mice that allows for the study of different moments to execute a serial order sequence consisting of two subsequences of actions. Using this task, we performed electrophysiological recordings in the premotor (M2) and primary motor (M1) cortices, and state-dependent optogenetic inhibitions of their cortico-striatal projections. We show that while both M2 and M1 contain activity modulations related to the execution of self-paced sequences, mainly, the premotor cortico-striatal projections contribute to the proper execution/structuring of these sequences.

Az achondroplasia a fogszabályozás szemszögéből
Authors: Gurdán Zsuzsanna , Szalma József , Benedek Pálma 
Published: August 2021

Összefoglaló. Az achondroplasia kialakulásáért az
FGFR3-gén mutációja tehető felelőssé, mely a porc
növekedési lemezében található chondrocyták érésében okoz zavart. Az
esetbemutatásban szereplő lánygyermeknél a születést követő első hónapban a
klinikai, laboratóriumi és röntgenvizsgálatok alapján achondroplasia
igazolódott. A klinikai tünetek közé tartoznak a rövid végtagok – különösen a
proximalis szegmensben –, a macrocephalia, a hypotonia és a horkolás. Szembetűnő
a középarc hypoplasiája. A középfül diszfunkciója tovább súlyosbítja a kórképet,
sok esetben megfigyelhető a hallás nagyfokú csökkenése, illetve kezelés
hiányában akár a hallás elvesztése. A közlemény részletesen bemutatja az
obstruktív alvási apnoe szindróma diagnózisrendszerét és kezelési alternatíváit,
hangsúlyozva az orthodontiai szempontokat. A fül-orr-gégészeti és a
fogszabályozó terápiának köszönhetően, a diagnózistól számított harmadik évre,
az alvási apnoe szindróma megszüntetésével a folyamatos pozitív nyomású
lélegeztetést el lehetett hagyni. A horkolás és az alvási apnoe szindróma
kezelése napjainkban egyre nagyobb hangsúlyt kap, melynek komplex kezelésében a
fogszabályozás is jelentős lehet. A harmonikus együttműködés és teamkezelés
betegünknél jelentős életminőség-javulást eredményezett. Orv Hetil. 2021;
162(17): 683–688.
Summary. Development of achondroplasia is due to the mutation of
FGFR3 gene, which disrupts the maturation of chondrocytes
found in the growth plate. The diagnosis of the girl in the present case study
was established based on clinical symptoms, laboratory tests and X-ray imaging
in the first month following childbirth. Clinical symptoms include shorter limbs
especially in the proximal segments, macrocephaly, hypotonia and snoring.
Hypoplasia of the midface is apparent. Dysfunction of the middle ear further
worsens the condition, in many cases severe hearing loss and, without treatment,
even deafness can be observed. The publication describes the diagnostic criteria
and therapeutic options of obstructive sleep apnea syndrome in detail, with an
emphasis on the orthodontic aspects. A comprehensive combined three-year
oto-laryngological and orthodontic treatment finally succeeded in controlling
the sleep apnea syndrome and it was possible to discontinue the continuous
positive airway pressure therapy by the end of the orthodontic therapy.
Nowadays, even more alternative therapeutic approaches are available to treat
snoring and sleep apnea syndromes, in which the role of orthodontics must not be
neglected. Harmonic collaboration and team work treatment resulted in a
significant improvement in the quality of life of our patient. Orv Hetil. 2021;

Összefoglaló. Az eltűnőepeút-szindróma ritka, rossz prognózisú
kórkép. Az epeutak progresszív destrukciójával, az intrahepaticus epeutak
eltűnésével jár, epepangáshoz, biliaris cirrhosishoz, végül májelégtelenséghez
vezet. A háttérben álló kiváltó okok között infekciók, ischaemia,
gyógyszermellékhatások, illetve daganatos megbetegedések szerepelhetnek. A
malignitások közül a leggyakrabban a Hodgkin-lymphomához társult formájával
találkozhatunk. Cikkünkben egy fiatal, Hodgkin-lymphomás betegünk esetét
szeretnénk bemutatni, akinél az icterus hátterében eltűnőepeút-szindróma
igazolódott, melyet egyéb okok kizárását követően szövettani mintavétellel
igazoltunk. A két ciklus ABVD-protokoll szerinti kezelést követő PET/CT az
alapbetegség tekintetében komplett metabolikus remissziót igazolt. A klinikai
javuláshoz azonban hosszú hónapokra volt szükség. Végül az epeúteltűnés
esetünkben reverzibilis folyamatnak bizonyult, az alapbetegség tekintetében a
komplett metabolikus remisszió elérésével az epeút-károsodás megállítható volt.

Summary. destruction and loss of the intrahepatic bile ducts leading
to cholestatis, biliar chirrosis and finally liver failure. It has been
described in different pathologic conditions including infections, ischemia,
adverse drug reactions and malignancies. The Hodgkin’s lymphoma-associated type
occurs most frequently among the forms of the disease of malignant origin. In
this report, we introduce the case of a 32-year-old male patient with Hodgkin’s
lymphoma, diagnosed with vanishing bile duct syndrome upon liver biopsy as a
root cause behind his icterus. The PET/CT has proven complete metabolic
remission after 2 cycles of ABVD chemoterapy. Clinical improvement, however,
occurred only after several months. Finally the loss of bile ducts proved to be
a reversible process, the complete metabolic remission of Hodgkin’s lymphoma
resulted in the regeneration of the bile ducts. Orv Hetil. 2021; 162(22):

Összefoglaló. Az elmúlt 40 évben a nemi kisebbségek speciális orvosi
ellátásához szükséges kutatások elterjedése és a publikációk folyamatos
növekedése figyelhető meg a külföldi orvosi adatbázisokban. A nemi vonzalom és
identitás sajátosságai nagyban befolyásolják a helyes diagnózis felállítását, a
szükséges kezelések és szűrések meghatározását, valamint a magas öngyilkossági
veszélyeztetettség miatt a prevenciós beavatkozási pontok körét is. Az orvosi
adatbázisokon kívül orvosszakmai szervezetek és oktatási-kutatási hátterű
klinikai intézmények is számos bevált gyakorlatról és irányelvről adnak
tájékoztatást. A szükséges ismeretek bővítésén túl előremutató lehet a nem
tudatos előítéletek csökkentése és az orvos-beteg kommunikáció elmélyítése. Orv

Summary. In the past 40 years, research studies related to the
special healthcare for sexual and gender minorities have become widely known and
the number of publications has increased in international medical databases. The
characteristics of gender attraction and identity have an impact on developing a
successful diagnosis, on determining the necessary screenings and treatments,
and on performing preventive intervention since the sexual and gender minorities
are at elevated risk for suicide. Apart from medical databases, best practices
and guidelines are also provided by healthcare professional organizations and
clinics committed to education and research as well. In addition to broadening
knowledge, reducing unconscious prejudices and improving the doctor-patient
communication would lead to a veritable leap forward in meeting the healthcare
needs of sexual and gender minorities. Orv Hetil. 2021; 162(32): 1267–1274.

Összefoglaló. A neurodegeneratív betegségek között az Alzheimer-kór
a leggyakoribb kórforma. Morbiditása és mortalitása világszerte egyre gyorsabb
ütemben növekszik, ezáltal szociális és gazdasági hatása is folyamatosan
fokozódó terhet jelent a társadalomra. Az elmúlt néhány évtizedben jelentős
előrelépés történt az Alzheimer-kór megismerésében, számos biomarker támogatja a
diagnózis felállítását, tüneti terápiát szolgáló gyógyszerek kerültek
bevezetésre. Az Alzheimer-kór klinikai megjelenése, lefolyása, viselkedése
rendkívül változatos képet mutat, felismerése a rendelkezésre álló eszközök
ellenére is kihívást jelenthet a nagy tapasztalattal bíró klinikusok számára is.
Munkánk céljául tűztük ki, hogy összefoglaljuk az Alzheimer-kór genetikai,
patológiai és klinikai jellemzőit, segítve ezzel a betegség jobb meg- és
felismerését. Bemutatjuk a jelenleg érvényben lévő patológiai és klinikai
irányelvek kritériumrendszereit, az újabb klasszifikációs szemléleteket.
Részletesen ismertetjük az Alzheimer-kór heterogenitását genotípus és fenotípus
szintjén egyaránt. Elemezzük a típusos és atípusos megjelenési formák
jellemzőit, a társuló kórállapotoknak a megjelenésre és a progresszióra

Summary. Alzheimer’s disease is the most prevalent neurodegenerative
disorder. Morbidity and mortality of Alzheimer’s disease are increasing
worldwide causing important social and economic burden on the society. Over the
past few decades, significant progress has been made in the understanding of the
pathogenesis of Alzheimer’s disease, several biomarkers support the diagnosis
and drugs for symptomatic therapy had been introduced. The clinical
manifestations and the course of Alzheimer’s disease have a variable picture, so
– despite the diagnostic opportunities – its diagnosis could be a challenge for
highly experienced clinicians as well. The aim of our work was to summarize the
genetic, pathological and clinical characteristics of Alzheimer’s disease, thus
helping to better understand and recognize the disease. We present the criteria
systems of the currently valid pathological and clinical guidelines with the
most recent classification approaches. The heterogeneity of Alzheimer’s disease
at both genotype and phenotype levels is described in detail. The
characteristics of typical and atypical manifestations and the effect of
co-pathologies on the appearance and progression of Alzheimer’s disease are also
discussed. Orv Hetil. 2021; 162(25): 970–977.
