PURPOSE Each ethnic group has a unique life style, including diets. Life style affects bowel movement. The aim of this study is to describe the results of colon transit time (CTT) tests in Korean children who had chronic functional constipation based on highly refined data. METHODS One hundred ninety (86 males) out of 415 children who performed a CTT test under the diagnosis of chronic consti...

BACKGROUND Hypertrophic cardiomyopathy (HCM) patients are more susceptible to suffer from heart failure with normal ejection fraction (HFNEF). Therefore, it is critical to evaluate the relationship between left ventricular filling pressure (LVFP) and HFNEF, even if a large proportion of HCM patients have normal LVFP at rest. The objective was to assess the correlation between exercise tissue Do...

Let G be a finite group, and let F be a formation of finite group. We say that a subgroup H of G is p F -normal in G if there exists a normal subgroup T of G such that HT is a permutable Hall subgroup of G and G G H H T H / ) ( is contained in the F-hypercenter ) / ( G F H G Z of G H G / . In this note, we get some results about the p F -normal subgroups and then use them to study the structure...

Trigeminocardiac reflex (TCR) represents now a nearly ubiquitary phenomenon in skull base surgery. Functional relevance of the intrainterventional TCR occurrence is hitherto only proven for vestibular schwannoma. In a retrospective observational study, 19 out of 338 (8%) enrolled adult patients demonstrated a TCR during transsphenoidal/transcranial surgery for pituitary adenomas. The 2 subgroup...

One of the main directions in group theory is study impact characteristic subgroups on structure whole group. Such include different $\Sigma$-norms a A $\Sigma$-norm intersection normalizers all system $\Sigma$. The authors non-periodic groups with restrictions such -- norm $N_{G}(C_{\bar{p}})$ cyclic non-prime order, which composite or infinite order $G$. It was proved that if $G$ mixed group,...

From 1981 to 1985 a prospective study on normal pressure hydrocephalus was performed. One of the aims of this study was to determine the site of CSF obstruction. Among 17 consecutive patients with a tentative diagnosis of normal pressure hydrocephalus, nine appeared to have non-communicating hydrocephalus most probably due to primary non-tumoural aqueduct stenosis. This unexpected finding provi...

This paper aims at studying solvable-by-finite and locally solvable maximal subgroups of an almost subnormal subgroup the general skew linear group $\GL_n(D)$ over a division ring $D$. It turns out that in case where $D$ is non-commutative, if such exist, then either it abelian or $[D:F]<\infty$. Also, $F$ infinite field $n\geq 5$, every normal $\GL_n(F)$ abelian.

‎suppose $n$ is a fixed positive integer‎. ‎we introduce the relative n-th non-commuting graph $gamma^{n} _{h,g}$‎, ‎associated to the non-abelian subgroup $h$ of group $g$‎. ‎the vertex set is $gsetminus c^n_{h,g}$ in which $c^n_{h,g} = {xin g‎ : ‎[x,y^{n}]=1 mbox{~and~} [x^{n},y]=1mbox{~for~all~} yin h}$‎. ‎moreover‎, ‎${x,y}$ is an edge if $x$ or $y$ belong to $h$ and $xy^{n}eq y^{n}x$ or $x...

‎In this paper we prove that a finite group $G$ having at most three‎ ‎conjugacy classes of non-normal non-abelian proper subgroups is‎ ‎always solvable except for $Gcong{rm{A_5}}$‎, ‎which extends Theorem 3.3‎ ‎in [Some sufficient conditions on the number of‎ ‎non-abelian subgroups of a finite group to be solvable‎, ‎Acta Math‎. ‎Sinica (English Series) 27 (2011) 891--896.]‎. ‎Moreover‎, ‎we s...

We prove that for “most” closed 3-dimensional manifolds M, the existence of a non singular one-form in given cohomology class u∈H 1 (M,ℝ)=Hom(π (M),ℝ) is equivalent to fact every twisted Alexander polynomial Δ H (M,u)∈ℤ[G/keru] associated normal subgroup with finite index H<π (M) has unitary u-minimal term.
