Factors affecting the immunogenicity of tetanus toxin fragment C expressed inLactococcus lactis (1996)

The relative immunogenicity of tetanus toxin fragment C (TTFC) has been determined in three different strains of inbred mice when expressed in Lactococcus lactis as a membrane-anchored protein (strain UCP1054), as an intracellular protein (strain UCP1050), or as a secreted protein which is partly retained within the cell wall (strain UCP1052). Protection against toxin challenge (20 x LD50) could be obtained without the induction of anti-lactococcal antibodies. When compared in terms of the dose of expressed tetanus toxin fragment C required to elicit protection against lethal challenge the membrane-anchored form was significantly (10-20 fold) more immunogenic than the alternative forms of the protein.
P‐ and E‐selectin receptor antagonism prevents human leukocyte adhesion to activated porcine endothelial monolayers and attenuates porcine endothelial damage (2018)

Selectin blockade may be useful as part of an integrated strategy to prevent neutrophil-mediated organ xenograft injury, especially during the early time points following reperfusion.
Limit of the Smallest Eigenvalue of a Large Dimensional Sample Covariance Matrix (1993)

In this paper, the authors show that the smallest (if $p \leq n$) or the $(p - n + 1)$-th smallest (if $p > n$) eigenvalue of a sample covariance matrix of the form $(1/n)XX'$ tends almost surely to the limit $(1 - \sqrt y)^2$ as $n \rightarrow \infty$ and $p/n \rightarrow y \in (0,\infty)$, where $X$ is a $p \times n$ matrix with iid entries with mean zero, variance 1 and fourth moment finite. Also, as a by-product, it is shown that the almost sure limit of the largest eigenvalue is $(1 + \sqrt y)^2$, a known result obtained by Yin, Bai and Krishnaiah. The present approach gives a unified treatment for both the extreme eigenvalues of large sample covariance matrices.
Micrornas Control Hepatocyte Proliferation During Liver Regeneration (2010)

Our results show that miRNAs are critical regulators of hepatocyte proliferation during liver regeneration. Because these miRNAs and target gene interactions are conserved, our findings may also be relevant to human liver regeneration.
Systematic Notes on the Genera Oroletes and Psolodesmus (Odonata) (1950)

Orolestes屬之已知種數有四，均分布東南亞一帶。J. Cowley氏（未刊稿）於檢討Fraser氏（1933）一文後，認為此四者之雄性尾部附屬器，彼此並無顯著可辦之區別，因之懷疑本屬原有分類體系之可靠性。M. A. Lieftinck氏（未刊稿）與筆者亦具同感，且以為此四種似可歸併為二種（附二亞種）。松村松年氏（1913）所記產於臺灣之Megalestes mirabilis（Oguma in litt..）一種，經筆者檢討結果，應改隸本屬。此外復於本系所藏標本中，得Orolestes koxingai Chen一新種，產自高雄恒春及臺北草山；其學名乃為尊崇國姓爺（鄭成功）而設，以紀念臺灣之光復也。Psolodesmus屬最初發現於福建廈門，後見於臺灣及琉球，迄今已知者僅二種（附一亞種）。經就其多量標本檢視雄性尾部附屬器及生殖器，比較雌雄二性之翅翼斑紋，並詳細分析其在臺灣之分布記錄，結果確認比二種實應歸併為一種（附二亞種）。

Misregulation of p-coumaroyl-CoA:monolignol transferase in Brachypodium distachyon (2014)

International audience
First Results from an Axion Haloscope at CAPP around 10.7  μeV (2021)

The Center for Axion and Precision Physics Research at the Institute for Basic Science is searching for axion dark matter using ultralow temperature microwave resonators. We report the exclusion of the axion mass range 10.7126-10.7186 μeV with near Kim-Shifman-Vainshtein-Zakharov (KSVZ) coupling sensitivity and the range 10.16-11.37 μeV with about 9 times larger coupling at 90% confidence level. This is the first axion search result in these ranges. It is also the first with a resonator physical temperature of less than 40 mK.
Practice harmonization workshops of EBMT: an expert-based approach to generate practical and contemporary guidelines within the arena of hematopoietic cell transplantation and cellular therapy (2023)

For hematopoietic cell transplantation (HCT) and cellular therapy (CT), clinical patient care is localized, and practices may differ between countries and from center to center even within the same country. Historically, international guidelines were not always adapted to the changing daily clinical practice and practical topics there were not always addressed. In the absence of well-established guidelines, centers tended to develop local procedures/policies, frequently with limited communication with other centers. To try to harmonize localized clinical practices for malignant and non-malignant hematological disorders within EBMT scope, the practice harmonization and guidelines (PH&G) committee of the EBMT will co-ordinate workshops with topic-specific experts from interested centers. Each workshop will discuss a specific issue and write guidelines/recommendations that practically addresses the topic under review. To provide clear, practical and user-friendly guidelines when international consensus is lacking, the EBMT PH&G committee plans to develop European guidelines by HCT and CT physicians for peers' use. Here, we define how workshops will be conducted and guidelines/recommendations produced, approved and published. Ultimately, there is an aspiration for some topics, where there is sufficient evidence base to be considered for systematic reviews, which are a more robust and future-proofed basis for guidelines/recommendations than consensus opinion.
Antibacterial Effects of Niridazole (1982)

Niridazole was shown to be an effective chemotherapeutic agent for mice infected intravenously with a niridazole-sensitive strain of Salmonella typhimurium. Death rates as well as bacterial counts per spleen were reduced, even in compromised animals. Histologic examination of spleens proved the reduction of inflammatory reaction due to Salmonella infection. A suppressive effect of niridazole treatment on immunity to challenge infection with S. typhimurium was not found, as demonstrated by infection with a niridazole-resistant strain of S. typhimurium.
Plasma surface engineering of biomaterials (2014)

The chemical and biological interactions between biomaterials and the outside environment such as tissues and body fluids depend on the surface properties. Low-pressure plasma-based and related technology offers the unique capabilities of modifying selected surface properties and enabling surface functionalization and fabrication of special surface structures to cater to clinical requirements such as mechanical strength, cyto-compatibility, nontoxicity, bacteria resistance, and so on. By using plasma-based techniques, the inherent favorable bulk properties of the materials and biomedical devices can be preserved while selective surface properties such as mechanical strength, hydrophilicity / hydrophobitcity, and chemical reactivity can be enhanced. In particular, plasma immersion ion implantation and deposition (PIII&D) is very useful to biomedical devices such as surgical implants because it is a non-line-of-technique and suitable for biomedical components with a complex shape such as bone fixators, scoliosis correction devices, cardiovascular stents, and artificial heart valves. In this plenary talk, recent research work performed in the Plasma Laboratory of City University of Hong Kong on plasma treatment of biomaterials is described. Examples will include bio-conductive coatings, biodegradable metals and polymers, antibacterial surfaces, and nanostructured biomaterials with favorable delivery and imaging properties.
Language and gender author cohort analysis of e-mail for computer forensics (2002)

Abstract. We describe an investigation of authorship gender and lan-guage background cohort attribution mining from e-mail text documents. We used an extended set of predominantly topic content-free e-mail document features such as style markers, structural characteristics and gender-preferential language features together with a Support Vector Machine learning algorithm. Experiments using a corpus of e-mail doc-uments generated by a large number of authors of both genders gave promising results for both author gender and language background co-hort categorisation. 1
Reconfigurable nano-kirigami metasurfaces by pneumatic pressure (2020)

Tunable/reconfigurable metasurfaces that can actively control electromagnetic waves upon external stimuli are of great importance for practical applications of metasurfaces. Here, we demonstrate a reconfigurable nano-kirigami metasurface driven by pneumatic pressure operating in the near-infrared wavelength region. The metasurfaces consist of combined Archimedean spirals and are fabricated in a free-standing gold/silicon nitride nanofilm by employing focused ion beam (FIB) lithography. The deformable spirals are instantly transformed from two dimensional (2D) to three-dimensional (3D) by the FIB-based nano-kirigami process. The 2D–to–3D transformation induces a dramatic irreversible change of the plasmonic quadruple modes and results in significant modulation in reflection by 137%. The suspended porous nano-kirigami metasurface is further integrated with an optofluidics device, with which the optical resonance is reversibly modulated by the pneumatic pressure. This work provides a strategy for tunable/reconfigurable metasurfaces, which are useful to build a promising lab-on-a-chip platform for microfluidics, biological diagnostics, chemical sensing, and pressure monitoring.
Imaging Wool Fiber Surfaces with a Scanning Force Microscope (1995)

Surfaces of wool scales are imaged using a scanning force microscope (SFM) and a field emission scanning electron microscope (FESEM). Atomic force microscope (AFM) images of wool fiber surfaces can be correlated with FESEM micrographs to provide complementary views of surface features. The AFM images are analyzed for scale height; on average there is a 21% increase when changing from air to water. The variability of scale height changes is large, and a model involving both swelling and scale move ment has been proposed. Lateral force microscope (LFM) images show complementary information to topographic AFM images and reveal the effects of surface treatment not available with other imaging techniques. Such images of treated wool surfaces reveal major inhomogeneities in friction, which are interpreted as differences in chem ical composition.
Indium-111-Labeled Human Nonspecific Immunoglobulin G: A New Radiopharmaceutical for Imaging Infectious and Inflammatory Foci (1992)

Indium-111-labeled human nonspecific immunoglobulin G (111In-IgG) is a newly developed radiopharmaceutical for imaging infectious and inflammatory foci. This article presents an overview of the literature concerning 111In-IgG scintigraphy. The current theory about the mechanism of accumulation suggests that 111In-IgG accumulates in lesions as a result of enhanced vascular permeability and subsequent entrapment of the radiolabeled protein. Human studies show excellent results in imaging bone and joint, abdominal, and intravascular infection. Of special interest is the ability to depict infectious foci in granulocytopenic patients. The value of 111In-IgG scintigraphy for detection of infection is compared with that of gallium-67, labeled-leukocyte, and technetium-99m (99mTc) nanocolloid scintigraphy. The significance of differences between 111In-IgG scintigraphy and two other new scintigraphic techniques, 99mTc-labeled IgG and 99mTc-labeled murine monoclonal anti-granulocyte antibody BW 250/183, are discussed.
Chemical Groups and Structural Characterization of Lignin via Thiol-Mediated Demethylation (2013)

Abstract A new approach to increase the reactivity of lignin by thiol-mediated demethylation was investigated in this study. Demethylated lignin was characterized by the changes in its hydroxyl and methoxyl groups, molecular weight, and other properties using titration and spectroscopy methods including FT-IR, 1H NMR, UV, and GPC. The total, phenolic, and aliphatic hydroxyl contents in lignin increased while the methoxyl content decreased after demethylation reaction, which indicated the occurrence of demethylation reaction. The results from FT-IR and UV analysis also indicated that the kraft lignin in this study contains mainly guaiacyl moiety and demethylated lignin has a higher guaiacyl content than original lignin. The average molecular weight of lignin decreased after demethylation reaction due to the cleavage of ether linkages in lignin macromolecules. No severe degradation of lignin was observed during the demethylation reaction.

THE INFLUENCE OF THYROXINE ON THYROTROPHIC ACTION OF PREGNANT MARES' SERUM GONADOTROPHIN IN RATS (1955)

The inhibitory influence of thyroxine on the response of the ovary of immature rats to gonadotrophic hormone has been indicated by a number of workers (Smith & Engle, 1930; Fluhmann, 1934; Leonard, 1936; Tyndale & Levin, 1937; Tolksdorf & Jensen, 1939; and Warner & Meyer, 1949). Recently, Kar et al. (1954) studied the nature of such inhibition and showed that thyroxine only diminishes the accelerated rate of follicular maturation caused by persistent gonadotrophin administration, but does not interfere with the hormonal activities of the ovary. They have further demonstrated that some of the pathological side-effects of precoccious ovarian stimulation with gonadotrophic hormone like cyst formation and follicular hemorrhage, could be blocked by simultaneous administration of thyroxine. These findings led them to postulate that thyroxine either slows down the rate of utilization of gonadotrophin by the ovarian tissue or causes greater inactivation of gonadotrophin at some unknown site.
Towards Accurate 3D Human Body Reconstruction from Silhouettes (2019)

We propose a novel computer vision system for reconstructing 3D body shapes from 2D images with the goal of producing highly accurate anthropomorphic measurements from a pair of images. We adopt a supervised learning approach that maps silhouette images to 3D body shapes via a convolutional neural network (CNN). We propose three key improvements over previous approaches: (1) Large-scale realistic synthetic data generation, including more realistic variations in segmentation noise and camera viewpoints. (2) A multi-task learning (MTL) approach to predicting multiple outputs such as shape, 3D joint locations, pose angles, and body volume. (3) A new network architecture that additionally takes known body measurements (e.g., height) and per-pixel segmentation confidence as input. Ablation studies show the improvement in accuracy due to the various components of our system. Results demonstrate that our system produces state-of-the-art results on body circumference errors. We also analyze the repeatability of our system in the presence of realistic camera, background, and pose variations. Our system achieves a vertex standard deviation of ~3mm on the [36] CAESAR dataset.
Peru upwelling plankton respiration: calculations of carbon flux, nutrient retention efficiency and heterotrophic energy production (2014)

Abstract. Oceanic depth profiles of plankton respiration are described by a power function, RCO2 = (RCO2)0(z/z0)b similar to the vertical carbon flux profile. Furthermore, because both ocean processes are closely related, conceptually and mathematically, each can be calculated from the other. The exponent (b), always negative, defines the maximum curvature of the respiration depth-profile and controls the carbon flux. When b is large, the C flux (FC) from the epipelagic ocean is low and the nutrient retention efficiency (NRE) is high allowing these waters to maintain high productivity. The opposite occurs when b is small. This means that the attenuation of respiration in ocean water columns is critical in understanding and predicting both vertical FC as well as the capacity of epipelagic ecosystems to retain their nutrients. The NRE is a new metric defined as the ratio of nutrient regeneration in a seawater layer to the nutrients introduced into that layer via FC. A depth-profile of FC is the integral of water column respiration. This relationship facilitates calculating ocean sections of FC from water column respiration. In a FC section across the Peru upwelling system we found a FC maximum extending down to 400 m, 50 km off the Peru coast. Finally, coupling respiratory electron transport system activity to heterotrophic oxidative phosphorylation promoted the calculation of an ocean section of heterotrophic energy production (HEP). It ranged from 250 to 500 J d−1 m−3 in the euphotic zone, to less than 5 J d−1 m−3 below 200 m on this ocean section.
Adult neurogenesis and brain regeneration in zebrafish (2011)

Adult neurogenesis is a widespread trait of vertebrates; however, the degree of this ability and the underlying activity of the adult neural stem cells differ vastly among species. In contrast to mammals that have limited neurogenesis in their adult brains,zebrafish can constitutively produce new neurons along the whole rostrocaudal brain axis throughout its life.This feature of adult zebrafish brain relies on the presence of stem/progenitor cells that continuously proliferate,and the permissive environment of zebrafish brain for neurogenesis. Zebrafish has also an extensive regenerative capacity, which manifests itself in responding to central nervous system injuries by producing new neurons to replenish the lost ones. This ability makes zebrafish a useful model organism for understanding the stem cell activity in the brain, and the molecular programs required for central nervous system regeneration.In this review, we will discuss the current knowledge on the stem cell niches, the characteristics of the stem/progenitor cells, how they are regulated and their involvement in the regeneration response of the adult zebrafish brain. We will also emphasize the open questions that may help guide the future research.
Acceleration of dermal tissue repair by angiotensin II (1997)

Angiotensin II is a naturally occurring peptide which has been shown to possess angiogenic properties. In the studies reported here, angiotensin II was shown to increase the proliferation of cultured bovine aortic arch endothelial cells in a concentration-dependent manner. Acute administration of angiotensin II in Hydron accelerated the repair of dermal injuries in a full-thickness excisional rat model. Additional studies were done to determine the best vehicle for delivery of angiotensin II to a dermal injury. Several vehicles, including 10% low-viscosity carboxymethyl cellulose, 4% medium-viscosity carboxymethyl cellulose, and 3% high-viscosity carboxymethyl cellulose, were found to be effective in this regard. Daily administration of angiotensin II for days 0 to 4 after injury (day 0 being the time of surgery) was determined to provide the optimal dosage for acceleration of wound repair by angiotensin II. In addition, dose-response studies indicated that angiotensin II accelerated wound repair in a dose-dependent fashion with 0.03 and 0.01 microg/rat/day of angiotensin II administered on days 0 to 4 being the minimally effective and no-effect doses, respectively. Administration of 100 microg/day of angiotensin II in 10% carboxymethyl cellulose for 5 days after injury to animals with impaired healing (steroid- and adriamycin-treated rats and diabetic mice) was also found to accelerate the rate of repair. In conclusion, angiotensin II accelerated the closure of full-thickness skin injuries in a dose-dependent manner in normal and impaired animal models.
Pushing the speed limit [ultrahigh-speed optical transmission technology] (2005)

Rapid increase in data traffic across communication networks have led to a demand for higher transmission capacities. In the past, there has been considerable interest in the use of WDM to increase the total transmission capacity. Since electrical signal processing is currently unavailable at this bit rate, many laboratories are investigating optical TDM (OTDM) technology. OTDM presents the challenge of investigating and developing high-speed optical signal processing and exploring the ultimate capacity for fibre transmission in a single wavelength channel. In this paper, the author discussed the advantages of OTDM transmission as well as recent ultrahigh-speed transmission experiments.
