Abstract:

In humans, the spleen is a highly compartmentalized organ. The structure, cell population, and functions are unique for each compartment. The red pulp comprises non-filtering lymphoid areas, the perifollicular zone that separates the red and white pulps, the red pulp cord tissue and sinuses, and the perivascular rim. B-follicles and T-cell areas can be found in the white pulp. The obtained specimens were divided into three groups: Group 1 (0 to 14 years), Group 2 (14 to 50 years), and Group 3. (Over 50 years). The results show diminish diameter of white pulp in spleen with aging in G1, G2, and

Abstract:

Biodeinking is a process of separating ink on the fiber surface by enzymes. This research was conducted to study and optimize biodeinking condition of sorted white ledger (SWL) by cellulase. Commercial cellulase (Sigma Aldrich, Singapore) at a dose of 0.25; 0.5; 0.75; 1; 2 U/g dry weight pulp was applied to the deinking of SWL and compared with blank. The deinked pulp was then analyzed for the fiber morphology and made laboratory hand sheets for the characterization of physical and optical properties.

Abstract:

Upgrading of white press cuttings into dissolving pulp was carried out by acidification followed by alkaline extraction. Acid treatment decreased ash content of white press cutting pulp from 11.25% to 0.33% at pH 2. The yield after acidification and screening was 87%. Alkaline extraction removed hemicelluloses and increased α-cellulose content to 92% with viscosity value of 4.3 mPa.s. The overall pulp yield after alkaline extraction was 76.6%. Alkaline extracted liquor contains 9.2% total organics, mostly pentose sugars in the oligomeric form. The produced dissolving pulp can be used for rayon

The normal migration route of B cells into follicular areas of spleen and lymph nodes is altered in the case of autoreactive cells that have bound self-antigen. To begin characterizing the molecular requirements for B cell migration into follicles, cells were treated with pertussis toxin (PTX), an inhibitor of signaling by many G protein-coupled chemokine receptors. Lymphocyte accumulation in the spleen is not inhibited by PTX and, therefore, the distribution of transferred cells was examined in this tissue.

Polyamidoamine epichlorohydrin (PAAE) is a permanent wet strength resin used in papermaking. When applied to paperboard, some amount of resin is retained in the sheet, and some is lost to the white water.

In addition, the influence of PAAE dosage, freeness, zeta potential, and pulp kappa number variability on PAAE retention is not well understood.

Abstract There has been increasing interest in using the plantation-grown white pine resource in Ohio. Potential uses include posts, poles, sawlogs, and pulp fiber.

Specific gravity or density is the simplest and most useful index to the suitability of wood for many important uses. It is a particularly important factor in the manufacture of pulp and paper because specific gravity largely determines the dry pulp yield from a given volume of wood.

The steps involved in lymphocyte homing to the white pulp cords of the spleen are poorly understood.

T cell entry to the white pulp is also reduced by blockade of LFA-1 and α4β1. The LFA-1 ligand, intercellular adhesion molecule 1 is critical for lymphocyte entry and both hematopoietic cells and radiation-resistant cells contribute to this requirement.

Abstract For the last 20 years, intravital two-photon (2P) imaging has been a powerful tool to visualize lymphocyte dynamics in mouse lymphoid organs such as bone marrows and lymph nodes. Although spleen is a key lymphoid organ for adaptive immunity against blood-derived antigens, the lymphocyte dynamics in the spleen are poorly understood because intravital 2P imaging of spleen is challenging. Visualizing the white pulp in the spleen where most lymphocytes are located requires the excitation light to propagate through the red pulp which contains a lot of blood, causing high light-scattering.

Abstract:

The disposal of wood ash and/or pulp and paper mill sludges is becoming increasingly more challenging as landfills are more difficult to site due to diminishing land availability and public opposition, as well as more costly to construct and operate because of increasingly stringent regulations. The most notable alternative to disposal that is receiving the attention of the forest industry is land application. The objective of this study, therefore, was to determine the influence of applying a pulp mill wood/sludge ash mixture on 1) various soil chemical properties of an Orthic Gray Luvisol an

Abstract:

Abstract Secondary lymphoid organs (SLO) provide the structural framework for the co-concentration of antigen and lymphocytes required for an efficient adaptive immune response. The spleen is the primordial SLO that evolved coincidentally with Ig-/TCR:pMHC-based adaptive immunity. B cells are indispensable for the formation and maintenance of SLO microarchitecture; their expression of lymphotoxin α1β2 (LTα1β2) is required for the LTα1β2:CXCL13 positive feedback loop without which SLO cannot properly form. Despite the spleen’s central role in the evolution of adaptive immunity, neither the init

Agents of immunomodulation are compounds that have the ability to balance the immune system throughout the body. The neem plant is one of the herbal plants that is often used as traditional medicine. Neem leaves (Azadirachta indica A. Juss) contain antioxidants that have the potential to be antiinflammatory, antiviral, and as an immunomodulatory agent. The constraint in giving medicine orally is the low bioavailability of drugs and the distribution of active compounds of herbal plants. This problem can be solved by packaging herbal plant extracts in nanochitosan. The purpose of this study was

Abstract Natural killer (NK) cells suppress antiviral immunity by killing a fraction of virus-specific CD4 T cells. This occurs during the first 3 days of infection, is perforin-dependent, and coincides with NK-cell localization in the splenic white pulp. While the receptors governing this NK-cell activity are ill-defined, it is clear that negative feedback mechanisms must exist to prevent excessive pruning of T-cell responses. Comparative transcriptome analysis of red pulp and white pulp localized NK-cells derived from late in the window of immunoregulatory activity (day 3) reveals increased

The spleen is an excellent lymphoid organ that harmoniously combines innate and adaptive immunity, helping to strictly remove blood-borne microorganisms and old erythrocytes from circulation. The functions of the spleen are focused on systemic circulation. Thus, it does not have afferent lymphatic vessels. It consists of two functionally and morphologically distinct sections: red pulp and white pulp. Red pulp is a blood filter that removes foreign substances and damaged and effete erythrocytes. It is also a storage site for iron, erythrocytes and platelets. As an example, it is the site of hem
