Instability of Hyperthermia Temperature for Magnetic Nanoparticles of Low Anisotropy Constant Due to Nonlinear Characteristics.

Magnetic nanoparticles (MNPs) subjected to external alternating magnetic field can induce heat in MNPs due to hysteresis, which is usually employed for tumor hyperthermia. An effective hyperthermia treatment should selectively kill the tumor cells without damaging the ambient healthy tissue. Hence, it is important for hyperthermia to correctly control the alternating magnetic field-induced temperature of MNPs in the tumor. This work develops a thermal model to analyze various forms of temperature-rise with time in magnetic nanoparticles for tumor hyperthermia. Results show that there are horizontal, linear rise, square root, exponential decay and abrupt temperature-rise lines with time in MNPs. The horizontal, linear rise, and square root temperature lines with time are consistent with the available experimental data. It is worthily noted that the form of abrupt temperaturerise with time can result in harm to the normal cells or tissue. If the abrupt temperature-rise does not be controlled and predicted well.

Processing Characteristics and Parametric Effects on Picosecond Laser Nanoscaled Patterning of Poly(methyl methacrylate).

Characteristics of picosecond laser processing for poly(methyl methacrylate) (PMMA) are studied in this text. Poly(methyl methacrylate) (PMMA) can be applied to micro- or nano-scale electronic devices. Short-pulsed laser is usually used for noncontact processing of nanoscale patterning of poly(methyl methacrylate) (PMMA). This study considers optical energy of laser to be transferred into decomposition energy of poly(methyl methacrylate) (PMMA). Using the condition of the energy balance at the decomposition interface, the variation of the ablation rate with the logarithm of the laser fluence is calculated for poly(methyl methacrylate) (PMMA) and agrees with the measured data. This study also discusses parametric effects of poly(methyl methacrylate) (PMMA) on the variation of the ablation rate with the logarithm of the laser fluence.

Thermal Transport Model of Short-Pulse Laser Microscale Ablation for Poly(methyl methacrylate) and Acrylonitrile Butadiene Styrene/Polyvinyl Chloride.

This study analytically investigates the picosecond laser ablation of poly(methyl methacrylate) (PMMA) and acrylonitrile butadiene styrene (ABS)/polyvinyl chloride (PVC). Pulsed laser ablation is a well-established tool for polymers. However the ablation mechanism used in laser processing of polymers is not thoroughly understood. This study utilizes a thermal transport model to analyze the relationship between the ablation rate and laser fluence. This model considers the energy balance at the decomposition interface. The calculated variation of the ablation rate with the logarithm of the laser fluence agrees with the measured data. This study also validates that the variation of the ablation rate with the logarithm of the laser fluence obeys Beer's law.

Analytical Study on Junction Temperatures of GaInN and AlGaN Ultraviolet Light Emitting Diodes.

Junction temperatures of GaInN and AlGaN UV LEDs are analytically investigated in this paper. GaInN and AlGaN UV LEDs have a wide variety of applications such as lighting, displays, spectrofluometry, photocatalytic processes, and high resolution optics. An analytical method is employed to analyze the junction temperature variations of GaInN and AlGaN UV LEDs with injection currents. The junction temperature is related to material properties, quantum efficiency, thermal resistance, and series resistance of LEDs. The results of GaInN and AlGaN UV LEDs predicted by this study agree with these obtained from emission peak shift method and forward voltage method.

Hyperthermia Temperature of Magnetic Fluid with Superparamagnetic Nanoparticles Subjected to an Alternating Magnetic Field.

This paper conducts the thermal analysis of magnetic fluid with superparamagnetic nanoparticles subjected to an alternating magnetic field. Magnetic fluid hyperthermia (MFH) provides a potential method for cancer treatment, which has fewer side effects than chemotherapy and radiotherapy. Superparamagnetic nanoparticles dispersed in water are suitable for safe application of MFH. A well-defined hyperthermia should only kill the cancer cells without injuring neighbouring normal tissue. A key factor for hyperthermia is to correctly control the alternating magnetic field-induced temperature of the magnetic fluid in the tumour. Therefore, this study develops a thermal transport model combined with a linear response theory of magnetic nanoparticle (MNP) heat dissipation to analyze the effects of parameters on temperatures in the magnetic fluid with superparamagnetic nanoparticles subjected to an alternating magnetic field. The results predicted by this model are compared with the available experimental data and show that the rise rates of temperature with time and temperatures along the radial direction are enhanced by the increase of MNP concentrations in magnetic fluid, the amplitude of magnetic field strength, frequency, and magnetization.

Complementary Chinese Herbal Medicine Therapy Improves Survival of Patients With Pancreatic Cancer in Taiwan: A Nationwide Population-Based Cohort Study.

BACKGROUND: Pancreatic cancer is a difficult-to-treat cancer with a late presentation and poor prognosis. Some patients seek traditional Chinese medicine (TCM) consultation. We aimed to investigate the benefits of complementary Chinese herbal medicine (CHM) among patients with pancreatic cancer in Taiwan. METHODS: We included all patients with pancreatic cancer who were registered in the Taiwanese Registry for Catastrophic Illness Patients Database between 1997 and 2010. We used 1:1 frequency matching by age, sex, the initial diagnostic year of pancreatic cancer, and index year to enroll 386 CHM users and 386 non-CHM users. A Cox regression model was used to compare the hazard ratios (HRs) of the risk of mortality. The Kaplan-Meier curve was used to compare the difference in survival time. RESULTS: According to the Cox hazard ratio model mutually adjusted for CHM use, age, sex, urbanization level, comorbidity, and treatments, we found that CHM users had a lower hazard ratio of mortality risk (adjusted HR = 0.67, 95% CI = 0.56-0.79). Those who received CHM therapy for more than 90 days had significantly lower hazard ratios of mortality risk than non-CHM users (90- to 180-day group: adjusted HR = 0.56, 95% CI = 0.42-0.75; >180-day group: HR = 0.33, 95% CI = 0.24-0.45). The survival probability was higher for patients in the CHM group. Bai-hua-she-she-cao (Herba Oldenlandiae; Hedyotis diffusa Spreng) and Xiang-sha-liu-jun-zi-tang (Costus and Chinese Amomum Combination) were the most commonly used single herb and Chinese herbal formula, respectively. CONCLUSIONS: Complementary Chinese herbal therapy might be associated with reduced mortality among patients with pancreatic cancer. Further prospective clinical trial is warranted.

Association of traditional Chinese medicine therapy and the risk of dementia in patients with hypertension: a nationwide population-based cohort study.

BACKGROUND: Patients with hypertension (HTN) reportedly have a higher risk of developing dementia. However, it remains unclear if use of Traditional Chinese Medicine (TCM), the most common form of complementary and alternative medicine, can help lower the risk of dementia for these patients. So the aim of the study was to investigate the effects of TCM on dementia risk among patients with hypertension. METHODS: This longitudinal cohort study used the Taiwanese National Health Insurance Research Database (NHIRD) to identify 143,382 newly diagnosed hypertension patients aged 20-90 years who received treatment between 1998 and 2007. Among them, 52,365 (36.52%) had received TCM after the onset of hypertension (TCM users), and the remaining 91,017 patients (63.48%) were designated as a control group (non-TCM users). All enrollees were followed until the end of 2012 to record the incidence of dementia. A Cox proportional hazards regression model was used to compute the hazard ratio (HR) of dementia in patients who received TCM. RESULTS: During the 15-year follow-up, 3933 TCM users and 10,316 non-TCM users developed dementia, representing an incidence rate of 8.41 and 11.55%, respectively, per 1000 person-years. TCM users had a significantly reduced risk of dementia compared to non-TCM users (adjusted HR = 0.76; 95% confidence interval [CI] = 0.74-0.81). The predominant effect was observed among those treated with TCM longer than 180 days (adjusted HR = 0.65; 95% CI = 0.62-0.69). Among the commonly used TCM products, Tian-Ma-Gou-Teng-Yin, Dan-Shen (Radix Salviae Miltiorrhizae), Chuan-Niu-Xi (Radix Cyathulae), Ge-Gen (Radix Puerariae), Jia-Wei-Xiao-Yao-San, and Jue-Ming-Zi (Semen Cassiae) were significantly associated with a lower risk of dementia. CONCLUSIONS: Results from this population-based study support the effects of TCM on reducing dementia risk, which may provide a reference for dementia prevention strategies.

Traditional Chinese Medicine Use among Patients with Psoriasis in Taiwan: A Nationwide Population-Based Study.

Traditional Chinese medicine (TCM) has long been used for patients with psoriasis. This study aimed to investigate TCM usage in patients with psoriasis. We analyzed a cohort of one million individuals representing the 23 million enrollees randomly selected from the National Health Insurance Research Database in Taiwan. We identified 28,510 patients newly diagnosed with psoriasis between 2000 and 2010. Among them, 20,084 (70.4%) patients were TCM users. Patients who were female, younger, white-collar workers and lived in urbanized area tended to be TCM users. The median interval between the initial diagnosis of psoriasis to the first TCM consultation was 12 months. More than half (N = 11,609; 57.8%) of the TCM users received only Chinese herbal medicine. Win-qing-yin and Bai-xian-pi were the most commonly prescribed Chinese herbal formula and single herb, respectively. The core prescription pattern comprised Mu-dan-pi, Wen-qing-yin, Zi-cao, Bai-xian-pi, and Di-fu-zi. Patients preferred TCM than Western medicine consultations when they had metabolic syndrome, hepatitis, rheumatoid arthritis, alopecia areata, Crohn's disease, cancer, depression, fatty liver, chronic airway obstruction, sleep disorder, and allergic rhinitis. In conclusion, TCM use is popular among patients with psoriasis in Taiwan. Future clinical trials to investigate its efficacy are warranted.

Association of Traditional Chinese Medicine Therapy and the Risk of Vascular Complications in Patients With Type II Diabetes Mellitus: A Nationwide, Retrospective, Taiwanese-Registry, Cohort Study.

With an increasing use of traditional Chinese medicine (TCM) in type 2 diabetes mellitus (T2DM), evidence of long-term benefit with adjunctive TCM treatment is limited. This study investigated whether the concurrent TCM treatment reduces the risk of vascular complications in T2DM patients by using a large population from National Health Insurance Research Database (NHIRD).We identified 33,457 adult patients with newly diagnosed T2DM using anti-diabetic agents from a random sample of one million beneficiaries in the NHIRD between January 1, 2000 and December 31, 2011. We recruited 1049 TCM users (received TCM over 30 days with a diagnosis of T2DM) and randomly selected 4092 controls as the non-TCM cohort at a ratio of 1:4 frequency-matched by age, sex, hypertension, hyperlipidemia, and index year. We investigated the prescription pattern of TCM and conducted a Cox proportional hazards regression to calculate the hazard ratios (HRs) of stroke, chronic kidney diseases (CKD), and diabetic foot between the 2 cohorts.In the TCM cohort, the prescription pattern of TCM was different between insulin and noninsulin patients. The most common herbs were Dan-Shen (Radix Salviae Miltiorrhizae) in noninsulin group and Da-Huang (Radix et Rhizoma Rhei) in insulin group. The most common formulae were Liu-Wei-Di-Huang-Wan in noninsulin group and Yu-Quan-Wan in insulin group. Although no significant reduction in the hazard ratio of CKD and diabetic foot, the incidence rate of stroke was 7.19 per 1000 person-years in the TCM cohort and 10.66 per 1000 person-years in the control cohort, respectively. After adjustment of age, sex, hypertension, hyperlipidemia, and antidiabetes agent use (including sulfonylureas, α-glucosidase, metformin, meglitinide, thiazolidinediones, and insulin), TCM cohorts were found to have a 33% decreased risk of stroke (95% CI = 0.46-0.97; P < 0.05).This population-based retrospective study showed that the complementary TCM therapy might associate with the decreased risk of stroke in T2DM, suggesting TCM as an adjunctive therapy for T2DM to prevent subsequent stroke.

Prescription patterns of traditional Chinese medicine for peptic ulcer disease in Taiwan: A nationwide population-based study.

ETHNOPHARMACOLOGICAL RELEVANCE: Peptic ulcer disease is a common digestive disease. There is a lack of large-scale survey on the use of traditional Chinese medicine (TCM) for the treatment of peptic ulcer disease. This study aimed to investigate the utilization of TCM for the treatment of peptic ulcer disease in Taiwan. MATERIALS AND METHODS: We analyzed a random sample comprised of one million individuals with newly diagnosed peptic ulcer disease between 2001 and 2010 from the National Health Insurance Research Database in Taiwan. Demographic characteristics and TCM usage, including Chinese herbal formulas and the single herbs prescribed for patients with peptic ulcer disease, were analyzed. RESULTS: A total of 96,624 newly diagnosed subjects with peptic ulcer disease were included. 14,983 (15.5%) patients were TCM users. People residing in highly urbanized areas, younger people and female (compared with male) were more likely to use TCM. With regard to the comorbidities, TCM users had a lower prevalence of coronary artery disease, chronic obstructive lung disease, diabetes mellitus and liver cirrhosis and stroke. The average time between onset of peptic ulcer disease and the first visit to a TCM clinic was 4.7 months. Majority of the patients (n=14,449; 96.4%) received only Chinese herbal remedies. The most frequently prescribed Chinese herbal formula and single herb was Ban-Xia-Xie-Xin-Tang (Pinelliae Decoction to Drain the Epigastrium) and Hai-Piao-Xiao (Os Sepiae), respectively. The core pattern analysis showed that combination of Ban-Xia-Xie-Xin-Tang, Hai-Piao-Xiao (Os Sepiae), Yan-Hu-Suo (Rhizoma Corydalis), Bei-Mu (Bulbus Fritillariae Thunbergii) and Chuan-Lian-Zi (Fructus Toosendan) was most frequently used for peptic ulcer disease. CONCLUSIONS: Our study identified the core prescription patterns of TCM for patients with peptic ulcer disease in Taiwan. Further basic and clinical studies are necessary to elucidate the efficacy and mechanisms.

Prescription patterns of Chinese herbal products for patients with fractures in Taiwan: A nationwide population-based study.

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional Chinese medicine (TCM) has been used in the treatment of fracture for thousands of years. However, large-scale surveys examing the utilization of Chinese herbal products (CHPs) for treating fractures and their related symptoms are lacking. This study aimed to investigate the prescription patterns of CHPs among patients with fractures in Taiwan. MATERIALS AND METHODS: The TCM usage in patients with fractures was analyzed using a sample of one million individuals randomly selected from the National Health Insurance Research Database who were newly diagnosis with fractures in 2001-2008, with a followed-up period through 2010. RESULTS: We identified 115,327 patients who were newly diagnosed with fractures in the study population. Among them, 4.97% (n=5731) adjunctively utilized TCM for fracture treatment. TCM users were mostly young or middle-aged, female, and resided in highly urbanized areas. With regard to the comorbidities of fractures, TCM users had a lower prevalence of coronary artery disease, chronic obstructive lung disease, diabetes mellitus, hypertension and stroke than non-TCM users, except for osteoporosis. Shu-jing-huo-xue-tang was the most frequently prescribed Chinese herbal formula, while Rhizoma Drynariae (Gu-sui-bu) was the most common single herb for patients with fractures. The CHPs were found to cover not only bone healing but also fracture-related symptoms. TCM users had lower medical expenditure for hospitalization for the first six months after incident fractures than non-TCM users (1749±2650 versus 2274±3159 US dollars, p<0.0001). CONCLUSIONS: Our study identified the TCM utilization for patients with fractures in Taiwan. Integration of TCM treatment reduced the medical costs for hospitalization. Further basic research and clinical studies to investigate the mechanism and clinical efficacies of CHPs are warranted.

Prescription patterns of Chinese herbal products for patients with uterine fibroid in Taiwan: A nationwide population-based study.

ETHNOPHARMACOLOGICAL RELEVANCE: Uterine fibroid (myoma) is one of the most common diseases in women. Although there are several studies on the efficacy of Chinese herbs, there is a lack of large-scale survey on the use of traditional Chinese medicine (TCM) for the treatment of uterine fibroid. This study aimed to investigate the utilization of Chinese herbal products for patients with uterine fibroid, prescribed by licensed TCM doctors in Taiwan. MATERIALS AND METHODS: A random sample comprised of one million individuals with newly diagnosed uterine fibroid between 2002 and 2010 from the Taiwanese National Health Insurance Research Database was analyzed. Demographic characteristics, TCM usage, the frequency as well as average daily dose of Chinese herbal formulas and the single herbs prescribed for patients with uterine fibroid, were analyzed. RESULTS: Overall, 35,786 newly diagnosed subjects with uterine fibroid were included. Majority of these patients (87.1%; n=31,161) had visited TCM clinics. Among them, 61.8% of their visits used Chinese herbal remedies. Patients less than 45 years of age tended to use TCM more frequently than elder patients. Gui-Zhi-Fu-Ling-Wan (Cinnamon Twig and Poria Pill) was the most frequently prescribed Chinese herbal formula, while San-Leng (Rhizoma Sparganii) was the most commonly prescribed single herb. CONCLUSIONS: Our study identified the characteristics and prescription patterns of TCM for patients with uterine fibroid in Taiwan. Further basic mechanistic studies and clinical trials are needed to confirm the therapeutic effects and mechanisms.

Non-Fourier two-temperature heat conduction model used to analyze ultrashort-pulse laser processing of nanoscale metal film.

This paper utilizes non-Fourier two-temperature heat conduction model to investigate the temperature field in nanometer-sized thin films irradiated by an ultrashort-pulse laser. Ultrashort-pulse laser processing for nanometer-sized devices is usually applied in MEMS and nanotechnology. For ultrashort-pulse laser interaction with metals, the two-temperature model was proposed to describe the heat transport in metals due to a substantial nonequilibrium between the electron and lattice temperature. For heat conduction in nanoscale devices, Fourier law is inadequate for describing the heat conduction in nanoscale due to the boundary scattering and the finite relaxation time of heat carriers. Therefore, in this work, the Non-Fourier two-temperature heat conduction model used to analyze ultrashort-pulse laser processing of nanoscale metal film. The result obtained from non-Fourier heat conduction equations is compared with the available experimental data. The parametric effects are also discussed.

Genistein inhibits tumor invasion by suppressing multiple signal transduction pathways in human hepatocellular carcinoma cells.

BACKGROUND: Genistein (Gen) exhibits anti-mutagenic and anti-metastatic activities in hepatoma cell lines. Gen has suppressive effects on tumor growth and angiogenesis in nude mice. Gen suppresses the enzymatic activity of matrix metalloproteinase (MMP)-9; however, the mechanism underlying its anti-invasive activity on hepatocellular carcinoma (HCC) cells is unclear. METHODS: In this study, the possible mechanisms underlying Gen-mediated reduction of 12-O-Tetradecanoylphorbol-13-acetate (TPA)-induced cell invasion and inhibition of secreted and cytosolic MMP-9 production in human hepatoma cells (HepG2, Huh-7, and HA22T) and murine embryonic liver cells (BNL CL2) were investigated. RESULTS: Gen suppressed MMP-9 transcription by inhibiting activator protein (AP)-1 and nuclear factor-κ B (NF-κB) activity. Gen suppressed TPA-induced AP-1 activity through inhibitory phosphorylation of extracellular signal-related kinase (ERK) and c-Jun N-terminal kinase (JNK) signaling pathways, and TPA-stimulated inhibition of NF-κB nuclear translocation through IκB inhibitory signaling pathways. Moreover, Gen suppressed TPA-induced activation of ERK/phosphatidylinositol 3-kinase/Akt upstream of NF-κB and AP-1. CONCLUSIONS: Gen and its inhibition of multiple signal transduction pathways can control the invasiveness and metastatic potential of HCC.

Investigation into pulse laser heating of nanoscale Au film using dual-phase-lag model.

In this study the thermal field is presented for pulse laser processing of nanoscale Au films. Fourier law is inadequate for describing the heat conduction in nanoscale process due to the boundary scattering and the finite relaxation time of heat carriers. In the regime where the particle description of electrons and phonons is valid, the Boltzmann equation is the most accurate option to model heat transfer in such problems. However, solving the Boltzmann equation is generally difficult due to involving three spatial, three momentums and one time. Dual-phase-lag (DPL) model is averaged over the momentum space and thus involves only spatial coordinates plus time, as in the Fourier equation. Therefore this paper utilizes the dual-phase-lag (DPL) model with scattering boundary condition to study the temperature field for laser processing of nanometer-sized thin films instead of Boltzmann equation. The results obtained from the dual-phase-lag heat conduction model, hyperbolic and parabolic heat conduction equations were compared with the available experimental data to validate the compatibility of the thermal models for analyzing the heat transfer in nanoscale thin film irradiated by laser. The temperature history at different locations of the thin film and the effects of boundary phonon scattering on the normalized temperature were also discussed.

Glycyrrhetinic acid inhibits ICAM-1 expression via blocking JNK and NF-kappaB pathways in TNF-alpha-activated endothelial cells.

AIM: To investigate the effects of glycyrrhetinic acid (GA), an active component extracted from the root of Glycyrrhizae glabra, on the expression of intercellular adhesion molecule-1 (ICAM-1) in tumor necrosis factor-alpha (TNF-alpha)-activated human umbilical vein endothelial cells (HUVEC). METHODS: ICAM-1 mRNA and protein levels were detected using RT-PCR and cell enzyme-linked immunosorbent assays. The adherence of human monocytic THP-1 cells labeled with [(3)H]thymidine to HUVEC was determined by counting radioactivity with a scintillation counter. The activation of mitogen-activated protein kinases as well as the degradation of I kappaB and nuclear factor-kappaB (NF-kappaB) or phospho-c-Jun in the nucleus were detected by western blots. NF-kappaB binding activity was detected using electrophoretic mobility shift assay. RESULTS: GA (50 and 100 micromol/L) significantly inhibits TNF-alpha-induced ICAM-1 mRNA and protein expressions, as well as THP-1 cell adhesiveness in HUVEC. GA selectively inhibited TNF-alpha-activated signal pathway of c-Jun N-terminal kinase (JNK), without affecting extracellular signal-regulated kinase 1/2 and p38. Furthermore, GA apparently inhibited I kappaB/NF-kappaB signaling system by preventing I kappaB degradation, NF-kappaB translocation, and NF-kappaB/DNA binding activity. Finally, pretreatment with GA or the inhibitors of NF-kappaB, JNK, and p38 reduced the ICAM-1 protein expression induced by TNF-alpha. CONCLUSION: GA inhibits TNF-alpha-stimulated ICAM-1 expression, leading to a decrease in adherent monocytes to HUVEC. This inhibition is attributed to GA interruption of both JNK/c-Jun and I kappaB/NF-kappaB signaling pathways, which decrease activator protein-1 (AP-1) and NF-kappaB mediated ICAM-1 expressions. The results suggest that GA may provide a beneficial effect in treating vascular diseases associated with inflammation, such as atherosclerosis.

Xia-bai-san inhibits lipopolysaccharide-induced activation of intercellular adhesion molecule-1 and nuclear factor-kappa B in human lung cells.

UNLABELLED: Xia-bai-san (XBS) is a traditional Chinese medicine that has been used clinically for centuries in Asian countries to treat some types of common cold and asthma-like diseases similar to infantile pneumonia and childhood bronchitis. In previous studies, XBS was found to suppress the inflammatory process induced in lungs of mice treated with lipopolysaccharide (LPS). PURPOSE: The present study was undertaken to examine the effects of XBS on LPS-inducible production of inflammatory cytokines, up-regulation of intercellular cell adhesion molecule-1 (ICAM-1), and activation of nuclear factor NF-kappaB in cultured human lung cells. PRINCIPAL RESULTS: Extracts of four raw herbs (Cortex mori, Cortex lycii, Radix glycyrrhizae, and Fructus oryzae) were used to prepare the decoction. XBS decreased the histological damage and up-regulation of ICAM-1 observed in lungs of mice treated with lipopolysaccharide (LPS). In cultured human pulmonary epithelial A549 cells, XBS and its components Morus alba and Glycyrrhiza uralensis suppressed the up-regulation of IL-8 and ICAM-1 in response to LPS. Production of TNF-alpha, IL-1beta, IL-6 and IL-8 by LPS-treated human THP-1 monomyelocytes was also suppressed by XBS. A549 cells expressed ICAM-1 in response to medium from LPS-treated THP-1 cells; expression was decreased by XBS. The adhesion of THP-1 cells to LPS-treated A549 cells were inhibited in the presence of XBS. Activation of NF-kappaB by LPS in A549 cells was suppressed by XBS, Morus alba, and Glycyrrhiza uralensis through inhibition of IkappaB phosphorylation; the concentrations at which suppression occurred were identical to those at which production of inflammatory cytokines and up-regulation of ICAM-1 were inhibited. MAJOR CONCLUSIONS: These findings support the hypothesis that XBS, Morus alba, and Glycyrrhiza uralensis inhibit the inflammatory process in lung tissue through suppression of the IkappaB signaling pathway. XBS may prove helpful in the management of asthma, various allergic disorders, sepsis, or any other condition associated with pulmonary inflammation.
