The intrauterine position occupied by a rodent fetus influences the amount of testosterone to which it is exposed before birth. Animals that are gestated between two male fetuses (2M) are exposed to higher circulating levels of testosterone than are animals positioned between two female fetuses (2F) and there are reliable differences in the reproductive physiology and behavior of 2M and 2F anim...

In the last decade, contact, almost contact, paracontact cosymplectic, and conformal cosymplectic manifolds carrying κ > 1 structure vector fields ξ have been studied by many authors, e.g. [2], [7], [11], [15]. In the present paper we consider a (2m + 2)-dimensional Riemannian manifold carrying two structure vector fields ξ (r ∈ {2m+1, 2m+2}), a (1, 1)-tensor field Φ, and a structure 2 form Ω o...

A linear code with parameters of the form [n,k,n?k+1] is referred to as an MDS (maximum distance separable) code. [n,k,n?k] said be almost (i.e., maximum or AMDS for short. near separable (in short, NMDS) if both and its dual are separable. Near codes correspond interesting objects in finite geometry have nice applications combinatorics cryptography. There many unsolved problems about codes. It...

Expression of MHC class I antigens requires the intracellular assembly of HLA-A,B,C H chains and beta 2-microglobulin (beta 2m). We have investigated the expression of free H chain, beta 2m, and their mRNAs in tissue sections of colon carcinomas that were defective for the native two-chain molecule. In all of these tumors, beta 2m protein and mRNA were found to be completely absent from the neo...

Numerous microbial pathogens, including Listeria monocytogenes, enter the host through the intestine. Although relatively little is known about the biological functions of intestinal intraepithelial lymphocytes (i-IEL), they are generally considered a first line of defense against intestinal infections. In the mouse, the vast majority of i-IEL express the CD8 coreceptor either as a CD8 alpha/al...

It is shown that the conclusions reached by Tereno are completely incorrect. We have recently shown that at the Event Horizon (EH) of a Sch. Black Hole (BH), the Kruskal derivative assumes a form [1] du dv → f(r, t, dr/dt) ±f(r, t, dr/dt) (1) because u → ±v as r → 2M . Although this limit attains a value of ±1 irrespective of f → 0,∞, or anything, Tereno [2] refuses to accept this. We have alre...

Investigations of serum total protein, albumin, alpha-1, alpha-2, alpha-2M, beta- and gamma-globulin changes are reported in 48 patients with craniocerebral trauma. Only alpha-2 and alpha-2M globulins showed important variations, the first rising to three to four times normal values (112% on average) and directly correlating with the amount of tissue lesions. Alpha-2M changes were rather irregu...
